This rang of wave band has greatly important applications in military because it located in the atmosphere window. Generally there are two ways to obtain this range of laser wavelength. One way is through optical parameter oscillation (OPO) from shorter laser wavelength and the other is through second harmonic generation (SHG) from longer laser wavelength. Firstly  the comparison between tow nonlinear crystals ZnGeP2 and AgGaSe2 is conducted for their nonlinear coefficient and damaging threshold in theory. The theoretical results show that the crystal AgGaSe 2 is more suitable for the SHG of pulsed TEA CO2 laser. When using pulsed TEA CO2 laser with wavelength of 9.3m to pumping AgGaSe2 SHG crystal  the wavelength of 4.65m is obtained. In the condition of repetition rate 100Hz  the upmost output power of single pulse is up to level of 1W  which corresponding efficiency of SHG is about 6%. The experimental results show that the polarization of laser beam has greatly influence on the SHG output of the crystal. Under the radiation of 3MW/cm 2 from fundamental wave and the right position for maximal SHG output in the crystal  when polarization of laser beam rotates 4.5  the SHG output of energy decrease about 30%. The research of this paper will make a foundation for further development of mid-infrared laser. 2010 Copyright SPIE - The International Society for Optical Engineering.   THE RELATIVISTIC COSMOLOGY UNDER THE HARMONIC CONDITION (Ⅱ)——THE POYNTING VECTOR AND REDSHIFT IN THE UNIVERSE 期刊论文  OAI收割 Science in China;Ser.A, 1990, 期号: 4, 页码: 1106-1114 作者:  Huang CG(黄超光);  Zhou PY(周培源) 收藏  |  浏览/下载：32/0  |  提交时间：2015/12/10 harmonic condition  red shift  intensity.   THE RELATIVISTIC COSMOLOGY UNDER THE HARMONIC CONDITION(Ⅰ) 期刊论文  OAI收割 Science in China;Ser.A, 1990, 期号: 1, 页码: 966-981 作者:  Huang CG(黄超光);  Zhou PY(周培源) 收藏  |  浏览/下载：19/0  |  提交时间：2015/12/10 harmonic condition  relativistic cosmology.
