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 cheap Laser Pointers.
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 portable laser can be supplied.
Can generate tens of millions of degrees of heat, and the resulting strong shock wave and Fan Chongji pressure. Precision range of the device can adapt to the order of 0.1 mm of the microspheres target, the target of a black hole, step target, all kinds of X-ray target such as a variety of target experimental needs, and has a single beam, dual-beam and two-way and targeting the function of the laser beams for laser fusion energy research and a variety of other physics research for an important experimental tool. June 1987 by the state-level identification. It has built the leading edge of the field of laser physics test provided a favorable means of cutting-edge scientific research and national economic construction of great significance. In the summer of 1986, General Zhang Aiping wrote an inscription for the laser on the 12th experimental device SG ". It can help the enterprise get the necessary material of portable laser.
Thus, the device is officially Aiping general experimental setup of laser No. handwritten inscription "SG Thus, the experimental device handwritten inscription SG named SG - Ⅰ Ⅰ, named SG since 1989, SG direct drive be 5000000 neutron yield, indirectly driven by the 10000 neutron yield, the shock wave pressure 0.8TPa received nearly the diffraction limit of Ne-like Ge X-ray laser gain saturation in 1990, SG National Science and Technology Progress Award. God light - II SG II 1993, "863" program established in inertial confinement fusion theme to further promote the development of the national inertial confinement fusion research and high-power laser technology in 1994, SG - I retired. It is due to the good purchase of portable laser.
SG - I run for eight years, made a number of world-class level of physical achievements in laser inertial confinement fusion and X-ray lasers, and other frontier areas. May 18, 1994, SG Ⅱ device project, the project was officially launched smaller scale than the SG - I device to expand to four times. SG Ⅱ installations in the domestic high-performance components, independently to solve a series of scientific and technical challenges to achieve the most advanced high-power solid state laser driver level, this area of our country a new leap forward. The system consists of laser systems and range systems, energy systems, optical automatic alignment system, the laser parameters measurement system, as well as environmental, quality, security systems, integration of hundreds of sets of various types of laser units or components. The factory should try the best to realize the purchasing goal of portable laser with the management cost as low as possible.
