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.   Noise characteristic of laser diode pumped orange-yellow solid-state laser by intracavity sum-frequency of KTP Phase matching II (EI CONFERENCE) 会议论文  OAI收割 ICO20: Lasers and Laser Technologies, August 21, 2005 - August 26, 2005, Changchun, China Tan H.; Gao L. 收藏  |  浏览/下载：29/0  |  提交时间：2013/03/25 The laser diode pumped Nd: YVO4 orange-yellow laser has been presented in this paper. The fundamental wavelengths of 1064nm and 1342nm oscillate simultaneous to generate the 593.5nm wavelength by intracavity sumfrequency of KTP nonlinear crystal phase matching II. The noise characteristic of laser output has been measured and analyzed in different pumping power. The relations between the amplitude noise of sum-frequency output and the longitudinal mode of fundamental frequency have been researched. The results show that the sum-frequency output is low noise if the one of fundamental wavelengths is single longitudinal mode. The experiments show that amplitude noise of intracavity sum-frequency laser is lower than that of intracavity doubled frequency laser with the same structure.   Evolution of persistent slip bands and its internal stress field in a fatigued copper single crystal 期刊论文  OAI收割 ACTA METALLURGICA SINICA, 2001, 卷号: 37, 期号: 5, 页码: 507-511 作者:  Yang, JH;  Li, Y;  Li, SX;  Ma, CX;  Wang, G   |  收藏  |  浏览/下载：21/0  |  提交时间：2021/02/02 fatigued copper single crystal  evolution of persistent slip band  internal stress field  simulation of dislocation structure   Structure at microcrack-tip and fracture in entire brittle solid 期刊论文  OAI收割 ACTA METALLURGICA SINICA, 2001, 卷号: 37, 期号: 5, 页码: 503-506 作者:  Li, ZC;  Liu, L;  Wu, X;  He, LL;  Xu, YB   |  收藏  |  浏览/下载：30/0  |  提交时间：2021/02/02 GaAs single crystal  low-load indentation  structure at crack-tip and propagation of crack  electron microscopy   Crystal structure, vibrational spectra and mechanism of dissolution of K2CaB8O26H24 期刊论文  OAI收割 ACTA CHIMICA SINICA, 2001, 卷号: 59, 期号: 4, 页码: 544-549 作者:  Jia, YZ;  Gao, SY;  Yu, KB;  Wang, B;  Xia, SP   |  收藏  |  浏览/下载：22/0  |  提交时间：2018/06/20 Double Salt Of Borate  Structure Of Single Crystal  Vibrational Spectra  Mechanism Of Dissolution
