The design of green laser pointer should be updated

The design of  green laser pointer  should be updated.
The past twenty years, committed to the development and application of neodymium glass laser drive - "SG" series devices, has made remarkable progress, and promote our inertial confinement fusion experiments and theoretical studies, and a place in the international arena. 1977, the Shanghai-ray machine using a 100 billion-watt laser system devices, inflatable glass shell targets irradiated nearly hundredfold body compression. Laser fusion research in China has entered an important stage of development of the step argument to the principle of implosion, and laid the foundation for future long-term sustainable development. In 1980, Wang Ganchang the proposal put forward to the construction of pulse power of 1 trillion watts solid state laser device, called a laser on the 12th experimental device (SG I). The loss caused by storage of  green laser pointer  should be reduced to the lowest level.The commission of green laser pointer also plays the important role
Laser on the 12th experimental device is built in the Shanghai Institute of Optics and Fine Mechanics, a large high-power laser experimental setup, located in Qinghe Road, Jiading District, Shanghai No. 390 light machine designed in 1983 by the Shanghai-ray machine, with a total construction area of 4612 square meters, four-story reinforced concrete frame structure, with a total height of 15 meters. The device outputs the two-beam diameter of 200mm, the strong beam, each beam of the laser peak power of up to one trillion watts, the pulse width of 1ns and 100ps, the wavelength of 1.053? M infrared light, the multiplier to 0.53? M, green of light. Physics experiment target chamber and a full set of diagnostic measuring equipment, to carry out the physical phenomena of laser heating and compression of the plasma and laser X-ray spectrum of basic research work in the laboratory. This is another goal of the good purchase of  green laser pointer .
In July 1985, the laser device on the 12th time and put into trial operation. The successful test run three laser shooting test, the valuable results achieved the expected goals. The device is the largest high-power neodymium glass laser device in the international arena is also one of the few large-scale laser works. It consists of the laser system, system range, measuring diagnostic system and the experimental environment engineering systems. The output laser power of up to one trillion watts of magnitude, while the laser time only billionths of a second one to ten billion one. Available lens to the size of 50 nm, can produce 10 trillion billion watts / cm 2 power density. This beam is focused on the surface of the material. More  green laser pointer  can be supplied.
Can generate tens of millions of degrees of heat, and the resulting strong shock wave and Fan Chongji pressure.
