Recently, with "high power laser material structure design and performance of the control" as the theme of the 239 held in Shanghai Oriental technology BBS. Member of the expert advice take measures to strengthen cooperation and strive to achieve new breakthroughs in the field of high power laser materials.
Congress President, Chinese academy of engineering dian-yuan fan in the inertial confinement fusion system present situation and tendency of the development of laser material "theme report, laser technology is one of eight cutting-edge technologies in the planning of medium and long-term science and technology in our country. Among them, the laser material is the core and basis for the development of laser technology, in the development of laser technology has the milestone significance and role.
Dian-yuan fan academicians, laser physicist, successively developed 1010 w, 1011 w, 1012 w and 1013 w device such as a large series of laser, and successfully applied in inertial confinement fusion, X-ray laser, high pressure equation of state, such as frontier physics research, to produce a series of international advanced level of achievements made important contributions.
Dian-yuan fan academicians engaged in the development of large laser devices and run for nearly 30 years. As one of the main technical director, has successfully developed laser power for billions and trillions of tile, billions of watts series high power nd glass laser system, to establish and develop has contributed to high power laser industry in China. The "laser 12 experimental device", is China's largest and one of the few international large laser engineering, the output power of 2 trillion watts. National identification of evaluation: "the comprehensive technical performance reached the international advanced level of similar equipment", "is a major achievement of laser technology development in our country, marked the our country has been in the field of high power laser has the comprehensive development capacity of one of the few countries". As standing members of the overall technology group, who led the project, head of the laser system, total mode field run command and device, in under the guidance of senior scientists kan-chang wang, Wang Dahang, under the leadership of the laboratory director member of Deng Ximing concrete, with hundreds of scientific research personnel, successfully solved a series of science and technology and engineering practical problems, make scientific research achievements into practical engineering facilities. This device running eight years in a row, for inertial confinement fusion, X-ray laser and extremely high pressure equation of state such as a large number of experimental studies, a number of international advanced level application results.
"Five-year" period, he proposed a larger number of "divine radiation Ⅱ" scheme, is listed as one of major projects, one of and as a project manager and chief engineer. After demonstration and technical design, the plan has been completed and reach the target. "The ninth five-year period, he devoted to the development of" divine radiation Ⅲ "device work. The cross-century giant laser engineering, is listed as national key projects. Dian-yuan fan overall technical team, and chief engineer of the project. Now completing the prototype design, and to begin construction.
On BBS at the same time, the experts say, laser manufacturing industry is the rapid development of our country, and penetration to various industries and areas, especially the laser weapon technology application and laser inertial confinement fusion technology application, etc. At present, the United States, Japan, European Union, Russia and other countries and regions are to develop the laser inertial confinement fusion technology, our country also laser fusion ignition engineering as one of the 16 big major r&d projects. The current fusion laser driver using neodymium doped glass as gain medium, but because of the low thermal conductivity of glass, limits the ability to work repetition frequency laser system. At the same time, the existing neodymium doped laser glass and so on can't meet the requirements of fusion energy laser driver. Therefore, the current laser material urgently looking for better performance.
