Chinese Academy Of Solid

Academician of Chinese Academy of Sciences Physics

, Xu Zuyan group developed solid-state laser (DPL) research breakthroughs, and on October 16 by expert test results: The average output power of 3799 W, repetition rate 1.1 kHz, pulse width 120 microseconds The optical conversion efficiency of greater than 50%.

Solid-state laser (DPL) set edge solid-state lasers and semiconductor lasers in one, with high efficiency, power, wave length, beam quality, small size, reliable performance and long life and many other advantages, is the major direction of development of laser technology . DPL in the defense of high-power, high-tech industry and cutting-edge research in many areas of science have a major application, Europe, the United States and other developed countries to support the development of national plans DPL and its underlying technology. China's "national long-term scientific and technological development (2006-2020)" will also be included among the 8 major cutting-edge technology.

"15" period, the CAS Knowledge Innovation Program with the support of major projects, Institute of Physics Academy of Sciences study group organized by Xu Zuyan advantage of 5 units of high-power solid-state laser systems technology and basic techniques in-depth research, has been awarded the DPL output of four kilowatt (continuous wave DPL 1354W, continuous wave heat capacity DPL 2277W, Q pulse train DPL 925W, quasi-continuous DPL 2076 watts). Recently, the group has achieved a breakthrough in the DPL research, and in October 16, 2006 by expert test results are:

Average output power 3799 W, repetition rate 1.1 kHz, pulse width 120 microseconds, optical conversion efficiency of greater than 50%.

Next, the group will carry out technical studies DPL system, including raising the output power, improved beam quality, expansion and regulation of wavelength, to accelerate the project and its major application of DPL, DPL to promote development and contribute to meet major national needs .
