 It is during the actual production of green laser pointer .
This theory is that the atomic composition of the material, a different number of particles (electrons) are distributed in the different energy levels of particles in the high energy level by a photon excitation, jump from high energy level (transition) to the low energy level, then will radiate excitation light of the light of the same nature in a particular state, a low light to stimulate the phenomenon of a light. This is called by the stimulated emission of light amplification, referred to as laser. Laser there are four main features: laser high brightness, high directionality, high monochromaticity and coherence. The high brightness of the laser: the brightness of solid-state lasers can be as high 1011W/cm2Sr. Not only that, with high-intensity laser beam focused by a lens. Repair of green laser pointer has been finished.
Thousands and even million-degree heat near the focus can be processed, which makes it possible to almost all materials. The high directivity of the laser: laser-directional so that it can effectively pass a longer distance at the same time, but also to ensure that focus the high power density, these two points are important laser processing conditions. High monochromaticity of the laser: high monochromaticity of the laser in order to ensure the beam can be precisely focused to focus a high power density. Laser coherence: coherence describes the phase relationship of the various parts of the light wave. Singular characteristic is the laser described above has been widely used in industrial processing. The result of the meeting of green laser pointer has been recorded.Penetration of blue-green sea water up to 600m above its propagation direction, and not to be intercepted by the enemy, and covert security, will greatly improve the Navy of its viability. Laser .The experiments show that 1kpa-100kpa back pressure, the solid propellant combustion by 5w-30w laser machine control, combustion can arbitrarily suspend and restart, thrust can be adjusted, thus greatly improve the performance of the propulsion system, there is great potential for development. Laser-guided. The guidance refers to the control and guidance of aircraft, in accordance with the selected reference flight path movement. The guidance system used in the military field satellite-guided, inertial guidance, terrain matching guidance and laser-guided. As one of the main guidance system, laser-guided a laser guided substances as the transmission of information to rely on the seeker, and automatically track the laser target shooting at the target reflected laser beam. It is the meeting of the technical detail of green laser pointer .
