It contains providing the continuous material of laser pointer .Mainly thanks to the comprehensive ability and a solid foundation of technical optics, precision machinery and electronics technologies accumulated over the years. High-power laser fusion research in 1964, Wang Ganchang independent of the proposed laser fusion initiative, the project began in 1965. After years of hard work to build a 10 billion watts of output power nanosecond laser device, in May 1973 and first played on the low-temperature solid deuterium target, at room temperature lithium deuteride target of deuterated polyethylene neutron. 1974 successfully developed the first multi-way slab amplifiers, the laser output power increased by 10 times, an order of magnitude increase in neutron yield. Decrypted to the heart contraction principle in the international arena, actively track and six-beam laser system was developed in 1976, target irradiation on the inflatable glass bulb.
Since the 1980s, the production of laser-guided missiles and laser-guided artillery shells and equipment number is increasing. ③ laser communications technology. Laser communication capacity, security and good, strong immunity to electromagnetic interference. Optical fiber communication has become the focus of the development of communication systems. Airborne and spaceborne laser communications systems and submarine laser communication system is also studying the development. ④ strong laser technology. Made tactical laser weapons, high-power lasers enable the human eye blinding and the photodetector failure. The use of high-energy laser beam could destroy aircraft, missiles, satellites and other military targets. Tactical laser weapons for blinding, air defense, close to the practical stage.  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.
Currently, APC system has passed the test, is preparing for combat. The performance of the United States envisaged in the future airborne laser weapons as follows: the laser medium Shots stored in the aircraft cabin 40; radiation target time for 3-5 seconds; laser power of 300 megawatts; a maximum range of 600 km; average cruising time of 48 hours. Main reason for early 2000 in preparation for a new Boeing 747-400F aircraft platform, the installation of airborne laser weapon demonstrator, however, new problems encountered during the installation process, a wider range of aircraft modification is the quality and appearance of the laser device does not meet the requirements of the U.S. Missile Defense Agency decided that the experiment be postponed until 2004-2005.
