Academician of Chinese Academy of Sciences Physics, Xu Zuyan group developed strong-state laser (DPL) investigation breakthroughs, and on October 16 by expert test results: The typical output power of 3799 W, repetition price 1.1 kHz, pulse width 120 microseconds The optical conversion efficiency of greater than 50%.
Strong-state laser (DPL) set edge strong-state lasers and semiconductor lasers in one particular, with high efficiency, power, wave length, beam top quality, modest size, trustworthy efficiency and extended life and numerous other positive aspects, is the major path of development of laser technology . DPL in the defense of high-energy, high-tech industry and cutting-edge study in numerous areas of science have a key application, Europe, the United States and other developed countries to help the improvement of national plans DPL and its underlying technologies. China’s “national lengthy-term scientific and technological development (2006-2020)” will also be incorporated among the 8 main cutting-edge technologies.
Strong-state laser (DPL) set strong-state lasers and semiconductor lasers benefit in one, with higher efficiency, power, wave length, beam high quality, little size, reputable overall performance and extended life and several other positive aspects, is the key path of development of laser technology . DPL in the defense of higher-power, high-tech business and cutting-edge investigation in a lot of areas of science have a significant application, Europe, the United States and other created countries to assistance the development of national plans DPL and its underlying technologies. China’s “national lengthy-term scientific and technological improvement (2006-2020)” will also be integrated among the eight largest advanced technologies.
“15” period, the CAS Understanding Innovation Plan with the help of main projects, Institute of Physics Academy of Sciences study group organized by Xu Zuyan benefit of 5 units of higher-power solid-state laser systems technology and simple tactics in-depth research, has been awarded the DPL output of 4 kilowatt (continuous wave DPL 1354W, continuous wave heat capacity DPL 2277W, Q pulse train DPL 925W, quasi-continuous DPL 2076 watts). Not too long ago, the group has accomplished a breakthrough in the DPL investigation, and in October 16, 2006 by expert test benefits are:
Typical output power 3799 W, repetition rate 1.1 kHz, pulse width 120 microseconds, optical conversion efficiency of higher than 50%.
Subsequent, the group will carry out technical studies DPL method, which includes raising the output energy, improved beam good quality, expansion and regulation of wavelength, to accelerate the project and its key application of DPL, DPL to promote development and contribute to meet major national needs .
