Process chart of green laser pointer system
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. 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.The green laser pointer would be no longer within the quality guarantee range if there’s artificial negligence such as falling in water. 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. 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.The green laser pointer would be no longer within the quality guarantee range if there’s artificial negligence such as lossing. 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. 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 200mW green Laser Pointer 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. The green laser pointer would be no longer within the quality guarantee range if there’s artificial negligence such as unsafe keeping.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. The working principle of laser radar and microwave radar similar to the use of electromagnetic radiation are the target and receives echo method, find, identify and indicate the target, only work in different bands. Laser radar applications in the military weapons qualification test, weapon fire control, tracking and recognition, command guidance, atmospheric measurements. Third, the laser-guided laser to track the target and as a means of transmitting information, missiles, artillery shells, aerial bombs and other technology-oriented goals. With high accuracy 100mW green laser pointer-guided, anti-electromagnetic interference capability, etc., which are widely used precision-guided weapons is an important guidance system. The green laser pointer would be no longer within the quality guarantee range because of other abnormal use.The type of laser-guided laser-guided types are: echo-type semi-active guidance, all active-type echo-guided and guided beam type. At present more general return type is the semi-active guidance.
Four strategic anti-missile 50mW blue violet laser pointer weapon, laser communications laser communication is to transmit information as a carrier of light, through the information (audio signal) is modulated onto light waves, and by the media (air, cable, etc.) of transmission.
