The need analysis of green laser pointer

Schematic diagram of the main structure and working principle of the free electron laser. "Missile defense insider," reported that after 20 years of development, the U.S. Navy already has been built the megawatt-class DF Chemical Laser (MIRACL) and the sea stone beam orientation (SLBD), they constitute the White Sands in New Mexico Missile Range in the high-energy laser system test device, "one of the main weapon has been used to test and validate the concept of several laser weapons. With the operational environment has changed dramatically in recent years, the U.S. Navy began its combat transfer from offshore operations into the littoral warfare, combat form of self-defense by attacking naval warfare into ships. green laser pointeris also famous in the European countries.
Thus, to deal with the growing cruise missile threat to become the main objective of the Navy's high-energy laser weapons program. As marine applications of lasers, to overcome the transport effect caused by the marine environment is critical. U.S. Navy has been working to develop high-power directed energy technology, the operating wavelength of chemical lasers, the laser emission before reaching its destination easy to atmospheric absorption, so had to abandon the development of high-power chemical laser weapons, but using lasers to protect ships against cruise missiles, research funding has never given up. Of FEL's by the U.S. Navy agencies believe is a better substitute for. The inauguration ceremony of the new manufacture base of green laser pointer will be held.
In June 2005, FEL 25 kilowatts of infrared laser, and a similar laser power in the world's highest laser. Naval Research behind the manager Jay Cohen, an industry conference in May 2005 said, "We will reach 100 kilowatts in the next five years, which is the minimum required to achieve destruction power." Although the free-electron laser at the same time also has the advantages of high efficiency, high power, laser quality. However, due to its huge size and high power reflector production difficulties, and can supply large amounts of electricity supply system is still not widely used. Solid-state lasers. Solid-state lasers is to use solid-state laser materials as a working substance, commonly used optically transparent crystal or glass as the matrix material, mixed with activated ions or other active substances constitute. Thegreen laser pointercompany has a long development history ofgreen laser pointer.
Among them, the glass laser material, made of uniform size materials for high energy or high peak power laser. Wide fluorescence spectrum, thermal efficiency is poor, work is not suitable for high average power. Crystal laser material with good thermal and mechanical properties, and narrow fluorescence spectrum, but difficult to obtain crystals of the large size materials. At present, secret trials conducted by the United States, its latest laser anti-aircraft weapons to shoot down unmanned aircraft. The latest laser weapons is solid laser weapon. Laser energy of 32 kilowatts unmanned aircraft destroyed in seconds. The United States armed forces jointly developed high-energy solid-state lasers. Thegreen laser pointercompany does well in the enterprise management.
Compared to chemical lasers, free electron lasers, solid-state laser volume and weight, better control, and the price is cheap, easily obtained. But in recent years, rapid development of its output power reached weapons-grade 100kW. However, only a portion of the light emission spectra of the solid-state laser weapon as the working substance absorption, together with other losses, and thus the energy conversion efficiency is still not high. Laser weapons development. Quickly because the United States in the development of laser weapons development, had been walking in the forefront of the world. The employee will get more bonus if the profit of green laser pointer is much more.
