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.   2-(2,4,6-Trimethylphenyl)-1,10-phenanthroline 期刊论文  OAI收割 Acta Crystallographica Section E, 2009 作者:  Yang PJ(杨培菊) 收藏  |  浏览/下载：18/0  |  提交时间：2012/09/21 single-crystal X-ray study  T = 293 K  mean (C–C) = 0.003 A°  R factor = 0.057  wR factor = 0.181  data-to-parameter ratio = 16.9   Dichlorido(2-chloro-9-mesityl-1,10-phenanthroline-k2N,N´) cobalt(II) dichloromethane hemisolvate 期刊论文  OAI收割 Acta Crystallographica Section E, 2008, 卷号: E64, 页码: m623 作者:  Yang PJ(杨培菊) 收藏  |  浏览/下载：22/0  |  提交时间：2012/11/09 single-crystal X-ray study  T = 293 K  mean σ(C–C) = 0.007 Å  R factor = 0.056  wR factor = 0.160  data-to-parameter ratio = 17.7   Central hole effect on Whispering-Gallery-Mode of triangular lattice photonic crystal microcavity (EI CONFERENCE) 会议论文  OAI收割 Optoelectronic Materials and Devices III, October 27, 2008 - October 30, 2008, Hangzhou, China 作者:  Zhang Y.;  Wang L.;  Wang L.;  Wang L.;  Wang Z. 收藏  |  浏览/下载：25/0  |  提交时间：2013/03/25 Whispering-Gallery-Mode (WGM) photonic crystal microcavity is a kind of photonic crystal application and can potentially be used for miniaturized photonic devices  such as thresholdless lasers. In this paper we study the WGM of photonic crystal microcavities focusing on the so called H2 cavities which are formed by removing seven air holes. The WGM in these large-size cavities has some advantages compared with single defect WGM in the view of real device applications. We further add a central air hole in the cavity region to analyze the effect on WGM in the microcavity by finite difference time domain (FDTD) and plane wave expansion (PWE). It is found that the tolerance of WGM is large enough for the fabrication of electrical injection structure. 2008 SPIE.   Catena-poly triaqua(4,4 '-bipyridine N,N '-dioxide-kappa O) dichloridocerium(III) -mu(2)-4,4 '-bipyridine N,N '-dioxide-kappa O-2 : O ' chloride monohydrate 期刊论文  OAI收割 Acta Crystallographica Section E-Structure Reports Online, 2007, 卷号: 63, 页码: M1430-U226 D.
