Through self-select mode cavity  lasers are designed to work at the border of stable zone instead  where large fundamental mode size in gain media can be reached. With increase of pumping power and self-aperture mode-selective effect  mode size would grow up automatically to a certain value suitable for monomode resonance. With double 180 W pump modules  acoustic Q-switch and LBO external frequency-doubled  over 28 W which M2 equals 4.5 quasi-CW output green laser and 52W 1.064 um IR output is obtained simultaneity. With the insertion or not of the harmonic separator by footswitch  high beam quality green  IR  and green IR lasers are obtained conveniently.   PIXE and ICP-AES analysis of early glass unearthed from Xinjiang (China) 期刊论文  OAI收割 nucl. instrum. methods phys. res. b, 2005, 卷号: 240, 期号: 1-2, 页码: 559 Zhang B; 承焕生; Ma B; 李青会; Zhang P; 干福熹; Yang FJ 收藏  |  浏览/下载：1979/195  |  提交时间：2009/09/22 external-beam PIXE  ICP-AES  early glass  China   Analysis of thin-walled composite box beam under torsional load without external restraint 期刊论文  iSwitch采集 THIN-WALLED STRUCTURES, 2002, 卷号: 40, 期号: 4, 页码: 385-397 作者:  Wu, YP;  Zhu, YL;  Lai, YM;  Zhang, XF;  Liu, SZ 收藏  |  浏览/下载：29/0  |  提交时间：2019/10/08 composite box beam  the theory of composite laminated plates  torsion without external restraint
