The intracavity frequency-doubled lasers generally requires a high fundamental power and harmonic power good output beam quality and stability, specific consideration should be given to the following factors and requirements: fundamental lasers with large mode volume and good mode; doubling crystal has a high conversion efficiency, high optical damage threshold; doubling crystal placed with a small waist spot at the fundamental cavity; frequency doubling the beam with small divergence angle and good stability. With particular attention to the optical damage threshold, in order to improve the second harmonic power, in certain fundamental conditions and the selected frequency doubling crystal, reducing the frequency doubling crystal at the fundamental waist, thereby increasing the power density is a very effective measures. However, the concomitant emergence of optical damage threshold of the crystal. The purchase plan can be performed based on the sales plan of 532nm green laser pointer.
In the pursuit of high-power intracavity doubling laser crystals of various forms of destruction will be very serious and should be special attention to the problem. These undermine the internal damage and surface damage. Caused by the destruction of these two reasons, the destruction of state, the solution is also different. The fundamental laser cavity design is a direct impact on the octave of optical power and beam quality. Understanding of spontaneous emission, stimulated absorption and stimulated emission. Understand the mechanism of laser-produced. Understanding the structure and working principle of laser. We have studied the hydrogen atom spectrum, and understanding of substance luminous knowledge. For ordinary light source, such as incandescent filament atomic absorption heat generated by the current acting excited to high energy level. The financing plan of 532nm green laser pointer can be made.
In the excited state, the atoms in a high energy level is unstable, spontaneously to a lower energy level transition, and at the same time emit photons, which is spontaneous emission. After one or more of the process, the atoms end up back in the ground state. Atomic spontaneous emission process, contains all frequencies of light, therefore, this common light source emitted light is not coherent light. Today we learn a different from the spontaneous emission of light, this light called laser. Abbreviation for Laser, Chinese is often transliterated as "laser". Learning characteristics and application of the laser: the coherence is high, parallel and high brightness. Have wide applications in holography, ranging, information storage, medical, etc.. And other corresponding plans of 532nm green laser pointer should be arranged and done.
We know that the laser is a kind of artificial light, the laser is generated? The laser mechanism. Atomic absorption energy level transition from a lower to a higher level, the energy absorbed is equal to the difference between the two energy levels; at a high level state of the atom is unstable and will spontaneously transition to a lower energy state, while emit photons, the photon energy equal to the level of difference. For ordinary light, such as we are familiar with the incandescent filament atomic absorption heat generated by the current acting excited to higher energy state; higher energy state of the atom is unstable and will spontaneously transition to lower energy state and emit photons. The sales plan of 532nm green laser pointer will greatly influence the following production plan preparation.
Spontaneous emission, the atoms in a random way back to the ground state, which means that each atom luminous moment, the direction of the initial phase is uncertain, luminous frequency is generally not the same. Therefore, the ordinary light emitted light is not coherent light. Atomic system in thermal equilibrium at room temperature, the majority of atoms in the ground state. If an incident photon energy is exactly equal to the atomic ground state and an excited state energy difference, then the atoms can easily absorb this photon transitions to this excited state. This transition is not spontaneous, in the stimulation of the incident photons, the so called stimulated absorption. Stimulated emission. If an incident photon energy is exactly equal to the atom a level the energy difference between the E2-E1. The purchase plan preparation of 532nm green laser pointer should be done quickly.

Then in the excited state E2 atoms may be the stimulation of this photon transitions to the lower energy state of the E1 and launch an identical photons of the incident photon, which is by the stimulated emission process. Subject to the stimulated emission of photons of incident photons have the same energy (frequency), but also have the same phase, polarization, and issued in the same direction. If this photon can produce a lot of this light is coherent light. The normal course of the majority of atoms in the ground state, if you use certain means to the excited atom system, making the number of atoms in the excited state E2 more than the number of atoms on the low-energy state E1 can. This state is called the inversion is a non-thermal equilibrium state. The financing plan preparation of laser pointer 1000mw needs to be finished timely.
At this time, an incident photon by stimulated emission of much greater probability than it is absorbed, can be the image that the incident was "Zoom". Mechanism: The principle of the laser is the use of the characteristics of the material atom by stimulated emission of radiation transitions. The generation of laser. Laser, stimulated emission optical amplification, "referred to, it is a special kind of light produced by artificial means. The laser is an important inventions of the 20th century, it has some features that ordinary light can not be compared, has been applied in a wide range of fields. Produce laser device called a laser, it is mainly composed of three parts, the work material, the pumping system and optical resonant cavity. The sales plan of laser pointer 1000mw should be as accurate as possible.
Lasers often use the work of substance name, such as the ruby laser, helium neon laser. Optical resonator is mainly composed of two parallel silver mirror, which is a total reflection mirror, and the other one is part of the mirror per cent see the transmission rate between the two mirror resonator wins. Laser work to try to make the working substance in the excited state, and its radiation photons fired at the other direction will soon escape the cavity, only movement along the axis of the photon bounces back and forth between the A and B, two mirrors, and in the work material lead to the same photon avalanche amplification, is the superior performance of the laser beam output from the side of the part of the reflective film. The reasonable purchase plan, financing plan and production plan of laser pointer 1000mw can be made and performed.
Include the following three steps: First, set the working substance (light-emitting material – can be gas, liquid or solid). Second pump: can a large number of electronic excitation to the energy level up the device in the ground state level. Common pump light, chemical energy (solid working material to run out of the irradiation, the gas substances multi discharge method). Inversion: a high-energy state of the electronic classified as low-energy states more than the number of electrons (the so-called "reverse" is a breakthrough because of this situation "normal" Boltzmann distribution law). Cavity (continuous bounces back and forth oscillation) induced the same frequency with the nature of the transition → magnified the same phase by stimulated emission of radiation. The manufacturer can arrange the suitable and reasonable purchase activity of laser pointer 1000mw.

It makes shooting light amplification by stimulated emission. Pumping device. It is the active medium and the device of the population inversion. Optical cavity. Active medium on which it can increase the amplification and transmission frequency to be selected. Types of lasers. First, gas lasers (He-Ne laser, argon ion laser, the "invisible killer" carbon dioxide lasers). Second, liquid, chemical and semiconductor laser (Chameleon dye laser, "death ray" hydrogen fluoride lasers, gallium arsenide laser). Third, the solid-state lasers (ruby laser, yttrium aluminum garnet laser). The supplier should prepare the production activity of laser pointer 1000mw well.

Accelerate the modernization of China's national defense technology laser technology has been applied in the military, ranging, direction, guidance, communications and tactical weapons, play an important role in order to improve the performance of weapons and equipment to improve the hit rate and reliability, and there are some The amount of exports. In order to obtain the coherent radiation of various wavelengths in order to adapt to the needs of a variety of applications, as one of the laser tuning techniques, the nonlinear optical tuning technology has been within the field of laser research focus. In recent decades, due to the discovery of a number of new high-quality nonlinear crystal, the use of the nonlinear crystal for nonlinear optical frequency conversion to the rapid development of products and wide application of various frequency-doubled lasers and optical parametric oscillators put to use is considered to be representative examples. They can show the star to others very correctly by 1000mw green laser.
The formation of a new industrial sector laser industry in China are gradually formed in the national economy, including a laser audio and video, laser communications, laser machining, laser medical treatment, laser detection, laser printing equipment and laser holographic industry is as a new economic growth point caused by the attention. For example, the country has more than 380 production laser audio-visual equipment (CD, LD, VCD, DVD), 1996, China has formed an annual output value of more than 8.5 billion yuan of new industries, the development of exceptionally rapid. Again, the use of holographic technology has opened up a laser embossed hologram anti-counterfeit trademarks and decoration industry, has also become a large-scale emerging industries. The customer can use 1000mw green laser to scare the dangerous animals away.
Photonics technology, basic curriculum design. Optical frequency multiplication principle and Technology. Optical frequency multiplication principle due to the dispersion phenomenon exists in the crystal, the direction of the frequency-doubling crystal in light, the fundamental frequency is different from the refractive index experienced by the optical second harmonic nω and n2ω. Menu in the frequency-doubled lasers, solid lines represent the refractive index of the extraordinary light dotted line represents the refractive index of a very light, the middle dotted line represents the refractive index of very light to change the incident angle. As can be seen from the figure, change the angle of incident light in the crystal, the refractive index curve of the middle of a very light change in the position of Figure 1064nm multiplier. 1000mw green laser can emit the very special red laser beam.
In the specific direction of light, 532nm second harmonic light and 1064nm base frequency refractive index can be equal to achieve the phase matching of SHG. Biaxial crystal phase-matching calculation is more complicated, there is not discussed in detail. Its phase-matching principle is the same. The solid line in Figure 1 represents the refractive index of the extraordinary light dotted line represents the refractive index of the very light, the middle dotted line represents the refractive index is very light in changing the incident angle. As can be seen from the figure, change the angle of incident light in the crystal, the refractive index curve of the middle of a very light change in the position of Figure 1064nm multiplier. Also, 1000mw green laser torch can be used for irradiance.
In the specific direction of light, 532nm second harmonic light and 1064nm base frequency refractive index can be equal to achieve the phase matching of SHG. According to (2.5) for further analysis, when? K ≠ 0, the second harmonic output power P (2W) along the length direction of the crystal varies periodically. Reach a maximum when the incident fundamental to the distance of π /? K, the multiplier output power, this distance is defined as the coherence length lc lc = π? K = π k (w)? 2k (w ) = λ (w) 4 [n (2 w)? n (w)] (2.8) if the fundamental wave in the crystal there is only one polarization state, the refractive index n (w), the phase matching conditions n (2 w) = n (w) (2.9) This is the phase matching phase matching. 1000mw green laser is used during the camping or travel.

The Los Alamos research team built a m tunable free electron laser, average power up to 3kW, 100s pulse width, the conversion efficiency of 0.4%. How to improve the energy conversion efficiency of the free electron laser is the main subject of the free-electron laser research. Chemical laser is based on a chemical reaction to create a population inversion and produce a class of lasers stimulated emission. Chemical laser material can be a gas or liquid, but most gas. Due to the unique nature of the chemical laser in the incentives and other aspects, usually classified as a separate branch of laser. And this kind of high powered laser pointer has the good and high quality and performance.
The chemical laser has the following three characteristics: chemical energy directly into the laser. Usually solid, gas, liquid or semiconductor lasers, chemical lasers, in principle, require additional power or light as the excitation source, but to use the energy released in the work material chemical reaction as the excitation energy. Most of the existing chemical lasers work, have flash or discharge of the supply part of the energy, but only in order to trigger the chemical reaction. Therefore, in some special applications, such as in the mountains, the wild lack of a place of power, chemical lasers demonstrate the unique advantages. The output of the laser wavelength is rich. Then the customer can know the quality and performance of high powered laser pointer better.
Chemical laser working substance may be the composition of the original participate in chemical reactions, it may be newly formed in the reaction of atoms, molecules, ions, or unstable atomic radicals. Launch the laser material is varied by the chemical reaction, therefore, the output laser wavelength of chemical lasers is quite rich, from the ultraviolet to the infrared, has been the micron band. High power, high-energy laser output. A vast reservoir of energy in chemical reactions, chemical lasers are the most promising access to the enormous power output of a laser. Such as hydrogen fluoride chemical laser, per kilogram of hydrogen and fluorine role will be able to produce 1.3 × 107 joules of energy. It is for the more useful and practical application of high powered laser pointer.
Chemical laser has broad application prospects in many fields, in particular the requirements of high-power situations, such as isotope separation, laser weapons. DF (DF) laser to shoot down the drone was already reported. Due to the needs of the application, the chemical laser in the types, structure, performance is also in constant development and improvement of the There is also a fiber laser for optical communication field, will be described in Chapter 9. Carbon dioxide laser. Carbon dioxide laser, referred to as "invisible," because it sends out a laser wavelength of 10.6 microns, "body" at the infrared region to the naked eye can not perceive it works a continuous, pulse two. Continuous manner to produce the laser power up to 20 kilowatts. The body of high powered laser pointer adopts the very special material.
Pulse generated a 10.6 micron wavelength laser is the most powerful laser. People have used it to "playing" a neutron in the nucleus. Carbon dioxide laser is a significant progress in laser development, the major achievement in light weapons and nuclear fusion research. The most common carbon dioxide laser discharge tube of a length of about 1 m. It generates the laser is invisible, bricks and mortar in brick enough to burn a dazzling white. The carbon dioxide laser is a CO2 gas laser gas as the working substance. The discharge tube is usually made from glass or quartz, which is filled with CO2 gas and auxiliary gas (mainly helium and nitrogen, a small amount of hydrogen or xenon). Ensure the high quality and performance of high powered laser pointer totally.

Electrode is generally a hollow cylinder of nickel; one end of the cavity is gold-plated reflecting mirror and the other end is a part of the mirror polished germanium or gallium arsenide. When high voltage electrode (DC or low frequency AC), a glow discharge in the discharge tube, germanium mirror at one end there is the laser output wavelength of 10.6 μm near the mid-infrared band; good tube . Discharge area of about one meter long can be obtained 40 to 60 watts of continuous output power. The CO2 laser is a gas laser. This is because it has some of the more prominent advantages: First, it has a relatively large power and high energy conversion efficiency. Closed tube CO2 lasers can be tens of watts of continuous output power. powerful laser pointer is very strict in parameter and technical requirement, perfect in technology and design, good and high in quality and performance but low in price.
This far exceeds the other gas lasers, the lateral flow of electric-excited CO2 laser can be hundreds of thousands of watts of continuous output. In addition, horizontal atmospheric pressure CO2 laser output pulse energy and power have reached a high level, comparable with the solid-state lasers. CO2 laser energy conversion efficiency up to 30 ~ 40%, which exceeds the normal gas lasers. Secondly, it is the use of the CO2 molecule vibration – rotation transitions between energy levels, spectra, there are dozens of lines of the laser output in the vicinity of 10 microns. The recently discovered high-pressure CO2 laser, and can even be continuous tunable output from 9 to 10 microns. It utilizes the advanced and perfect production method of powerful laser pointer.
Third it output band is just the atmospheric window (ie the atmosphere to the high transparency of the wavelength). In addition, it also has a high optical quality of the output beam, coherence, narrow linewidth, stable, etc.. Therefore it has many applications in the national economy and national defense, such as used in the processing (welding, cutting, punching, etc.), communications, radar, chemical analysis, laser-induced chemical reactions, surgery, and so on. CO2 laser coherent imaging radar for airborne anti-tank missiles, precision-guided study, started in 1977 by the Massachusetts Institute of Technology's Lincoln Laboratory, the laboratory in 1981, successfully developed and demonstrated test. More functions can be added to powerful laser pointer.
As early as the late 1970s, the U.S. Defense Advanced Research Projects Agency (Defence Advanced Research Projects Agency) CO2 laser coherent imaging radar as the main direction of the second-generation cruise missile guidance system, now to the technical stages of maturity. DARPA and the U.S. Air Force Aeronautical Systems Division, chaired by the advanced cruise missile guidance (CMAG, Cruise Missile the Advanced Guidence) pre-research project, completed in 1977 and 1989 research projects, and completed a flight demonstration experiment, further development of the CO2 laser initiative imaging radar seeker prototype. The CMAG technology has been applied on the advanced strategic air-launched cruise missiles, the AGM-129A. These are used to enhance the quality and performance of powerful laser pointer.
So that the target accuracy from 40m up to 3m, an order of magnitude. Former U.S. wheat ? Road weather for the Air Force developed a CO2 laser coherent imaging radar in 1988, a prototype demonstration is expected to be installed on the Tomahawk (Tomahawk) modified cruise missiles. Laser safety classification. Grade Ⅰ: the laser will not pose any known degree of injury. Class IA: This is a special level, referred to as "not suitable for direct eye view" of lasers, such as supermarket laser scanner. The maximum limit of this level laser power 0.4 mW. Class II: the low-power visible lasers, the transmit power than the I-level is high, but the radiated power is not higher than 1 mW. Automatic defense reaction of human light to protect humans from harm. And the coating of powerful laser pointer will be difficult to be damaged.

Furthermore, excimer lasers, free electron lasers, chemical lasers, fiber lasers and other laser devices of the new development and a better prospect. This section is only for a brief introduction of these lasers. Excimer laser. Under normal conditions, atoms can temporarily combine into unstable molecules in the excited state, called excimer, referred to as the excimer. The substance of the work of the excimer laser is the excimer gas. Since the advent of the first excimer laser in 1970, it successfully developed a variety of excimer lasers in isotope separation, photochemistry, pumped dye lasers has made a contribution. In the development of laser weapons, it is also one of the very promising laser. This high power laser pointer is the good tool and assistant for the customer.
Excimer laser treatment of myopia has also achieved good economic and social benefits. To date, the excimer laser is more and more, the incentives also continue to improve power and increased efficiency. Pulse energy has reached the order of one hundred joules, pulse peak power of kilowatts or more, the repetition rate of 200 times / sec, the beam divergence angle 0.15mrad. The excimer laser is characterized by distinctive features: the level structure. Figure (5-33) shown in A indicates a higher excited state, B the upper level, C is the ground state. Ground level of the lower laser level. As the ground state to the exclusion of state or weakly bound state is very unstable, it moves along the potential curve C to the nuclear separation R increases fast in the direction until eventually dissociate into atoms. Here is the design and technology of high power laser pointer.
The ground state molecule will disappear. The ground state molecules of life is very short, 10-13s order of magnitude. Excitation state of the bound state, the level lifetime of 10-8s order of magnitude, than the ground state stability in the internuclear distance R0 is very easy to form B, C, between the inversion distribution. The excimer The level structure. Excimer from the excited state to ground state transition from the bound state transition to the free state (weakly bound state or repulsive). Such terminated reversal transition, the approximation of the lower level is empty, so there is no low energy level is filled. Means that the excimer transition is not self-terminate "transition. – The number of excimer reversal there, it is easy to accumulate a considerable amount of particle number, and likely to get larger the population inversion and a larger gain. It will determine which process and production method of high power laser pointer.
The ground state lifetime is very short, even ultrashort pulse case, the ground state can also be considered to be empty, so the excimer system is particularly beneficial to produce the giant pulse. Laser level is the ground state, with virtually no radiation loss. Therefore, a high quantum efficiency, which is the main reason for the excimer laser may reach a high efficiency. Rapid dissociation ion laser level, and thus lengthen the pulse width and high repetition rate are not difficult. Excimer fluorescence spectroscopy with a continuous, it can be made of the frequency tunable devices. Laser level lifetime is very short, in order to achieve population inversion, the pump pulse rise time is short. Therefore, for work in the short wavelength UV laser, excimer system to achieve an effective pump. And manufacturing process of high power laser pointer is used.
Not only requires a large pump power, and requires a fast rise time. In order to meet the requirements of the pump source to take a lot of pump way, commonly used in the following two types: electron-beam pump. Electron gun to produce high-energy, fast rise time of the electron beam pulse, the electron beam fired excimer District, to stimulate the active medium. E-beam pump can be divided into three forms: (1) horizontal pump, the electron beam direction and the laser optical axis is vertical. In this way a simple structure, small size, the drawback is the low use of electron beam energy. ② pumped, the electron beam direction parallel to the laser optical axis. Pumped energy efficiency to be improved, but the need to increase the used electron beam oriented huge bunching field. Here will introduce a very short and small type high power laser pointer.

Widely used in silicon material germanium materials. Application of laser technology in the machine tool industry: Machine Tool and skateboard straightness measurement prior to the advent of the laser collimator, collimation technology pull wire method or the use of optical collimating telescope, but they are there are some disadvantages. As the laser has a good direction, so it is the ideal light source collimator technology. Laser alignment technology has been in large, Precision Machine Tool and skateboard straightness measurement applications. Straightness measurement, laser collimator with the optical collimating telescope has the following advantages: the measurement results without the need for mathematical treatment. Error curve of the survey record result is the movement of the machine tool table. These are for the mass production of laser stage lighting.

In the measurement of long rails, optical collimation telescope optical losses, so the imaging is not clear enough. The laser collimator is no such shortcomings, the straightness of the rail movement can measure up to 20mm or more. Laser cleaning: laser cleaning method is a new cleaning method, it appears from the laser's unique material selectivity: a certain power YAG laser can be easily cut metal but can not penetrate the thickness of a sheet of paper, while a certain power The CO2 laser can easily cut the wood plastic but not cutting the hole of an aluminum foil net residual ink film hoarding the mostly non-metallic material and textured materials for the metal. The first article normally means the certain samples of laser stage lighting.
This selective application of the laser material to provide the space, using the CO2 laser cleaning technology can be successfully vaporization but then textured on the accumulation of material in no way undermine [5]. Laser cleaning technology has the following characteristics: it is a dry-cleaning, no cleaning solution or other chemical solution, so there is no chemical cleaning of the environmental pollution problems, and cleanliness; scope and application of substrates to remove dirt a very wide range; laser cleaning is a non-contact processing, can be easily remote operation, such as through the optical fiber transmission, cleaning the site of some methods is not easy to reach and close operation to avoid the traditional cleaning method of cleaning surface mechanical The force is easy to damage the shortcomings of the surface. It is not the very first piece of laser stage lighting.
