Teaching requires a general understanding of laser technology knowledge, to master laser technology in the military for general use, and general measures against the master laser. Section II outlines the main content of laser technology, laser applications in the military and protection against laser Section III outlines a laser, what is the use of laser light laser, thermal, electrical, chemical, or nuclear energy, external energy to motivate the material to occur by stimulated emission of radiation arising from a special kind of light. ("Encyclopedia of China" military roll P608) The 100mW laser pointer company has ten-year experience in manufacture and R&D.Second, the laser produces spontaneous emission by stimulated absorption of atoms in the excited state is very unstable and will return to ground state after release of atoms, known as spontaneous emission. Two-photon stimulated emission in the frequency, phase, exactly the same direction of propagation. Third, the laser characteristics of the laser with ...
... high brightness, good color, good direction, coherence and good features. Good directional divergence angle is small: the same propagation distance, small spot size, high brightness? Light source of strength? 1 mW hydrogen-neon laser: 44 Sun brightness: 1? By high-brightness laser beam is focused, can produce millions of units of high temperature and pressure. Thousandths of a second to make any metal vaporization. Fourth, the laser (a) laser laser structure is to produce the laser device. This 200mW Laser Pointer company owns several national patents.It is mainly from the work material, excitation source and the resonator consists of three parts. Laser Figure (b) the types of lasers??? By operating (working) way points, a continuous wave, single pulse, repetitive pulse and wavelength tunable lasers; by incentives points, light excitation, electrical stimulation, thermal excitation, Chemical excitation and nuclear excitation lasers; by working substance, into solid, gas, semiconductor, dye, chemical, and free electron lasers. Laser types 1, solid-state lasers. As a solid material with lasers work material. These lasers are characterized by small, rugged, high power. 2, gas lasers.There are 13 engineers in this 10mW blue violet laser pointer company. Gas as a working laser material. Its characteristics are able to pulsed and continuous work in two ways. 3 types of lasers, semiconductor lasers. Semiconductor lasers used as the working substance. Its biggest feature is the small size and variety of high efficiency, easy to use. 4, the dye laser. Working substance is an organic dye material. It features continuously adjustable operating wavelength (wavelength distribution from 0.32 to 1.3 microns), mainly for scientific research. 5 types of lasers, chemical lasers. Provide energy through chemical reactions, the formation of stimulated emission of the laser. Its characteristics are: high frequency, photon energy, penetration, damage to high performance. 6, free electron lasers. Work material is electron beam. It features high output power, thus becoming the device of choice for strategic laser weapons. 26 technicians are employed in this green laster pointer company.Section II in the military application of a laser rangefinder two, three laser radar, laser-guided four or five laser communications, laser weapons, a laser rangefinder laser ranging principle is: the target by a laser signal, the laser signals to and from the measuring point and the time spent between the target to derive the distance. Laser ranging applications in military laser rangefinder can be used in the military topographic survey, ranging front lines, tanks and artillery ranging, measuring cloud, aircraft, missile and satellite height. China developed two laser range finder, laser radar, laser beam search, track and measure the activities of the target device called LIDAR.
