1964 launch of the "6403" high-energy neodymium glass laser systems, high-power laser systems and nuclear fusion research studies in 1965, and developed 15 kinds of military laser machine and other key projects in 1966 to develop, due to the integrated and technically tough, strong traction and led to the development of all aspects of laser technology in China. Our laser science and technology, although it suffered a "Cultural Revolution" years of calamity, but the support by means of key projects, is still struggling to survive and made valuable progress. High-power laser systems and nuclear fusion research in 1964 independently by laser fusion Ganchang initiative, in 1965 began to study the project. After several years of efforts to build the output power 10 (superscript 10) watts of nanosecond laser device, and in May 1973 for the first time in the low-temperature solid deuterium target, at room temperature lithium deuteride deuterated polyethylene target and hit the neutron . 1974 successfully developed China's first multi-pass slab amplifiers, the laser output power increased by 10 times, the neutron yield increased by an order of magnitude. After compression to the heart of the principles of international decryption actively tracking and developed in 1976 into six-beam laser system, the target of a pneumatic bulb exposure, gained nearly a hundred times in the body compression. A major breakthrough in this series, so that our laser fusion research advanced in the world, but also for future long-term sustainable development laid the foundation. "6403" high-energy neodymium glass laser system started in 1964, and finally determine the thermal effect is technically fundamental technical obstacles, dismount in 1976. This project supports the development of high-energy laser technology contribution history can not be ignored, it makes the level of laser technology on a higher level. The results mainly in: (1) has built a project the size of large diameter (120 mm) Oscillation - amplified laser system, the maximum output energy of 320,000 joules; improve the beam quality after 30,000 joules. (2) implement the system integration technology, successfully carried out shooting experiment, indoor 10 meters breakdown 80 mm aluminum target, two kilometers from the breakdown 0.2 mm aluminum outdoor rake, and systematic study of the biological effects of intense laser radiation and material damage mechanism. (3) The first reveals the light on the laser system itself photodamage phenomena and mechanisms. (4) The first time the importance and physical connotation depth and understanding of laser beam quality, beam quality using a suite of innovative technologies, such as ten thousand joules level unstable resonator laser, sheet laser oscillation - scan Amplified The laser system, the wedge method beam quality diagnosis. (5) laser components and supporting technology breakthrough to improve, such as low absorption high uniformity neodymium glass melting technology, high-energy pulsed xenon, high strength dielectric film, large-diameter (1.2 m) of optical precision machining. (6) to cultivate and foster a batch of technical backbone of the team.
