glw meaning in Chinese

无暇疵的钻石

Some researches about frequency doubling are made , and two methods to improve intensity of second frequency generation are given . we realized q - switched 532 nm laser , by using nd : gdvo4 as laser crystal , using cr4 + : yag as saturable absorber , using ktp as intra - cavity frequency doubling crystal . average power of 109mw , repetition of 40khz , pulse width of 30ns , pulse energy of 2 . 6uj , peak power of 91w are obtained
4 .对倍频理论进行研究和分析:讨论两种提高二次谐波功率密度的方一法;实验匕在国内首次实现ld端面泵浦nd : gdvo4 / ktp ，用cr4 + : yag作为可饱和吸收片的绿光激光器，腔内倍频得到了平均功率为109mw 、重复频率为40khz 、脉宽为3ons 、单脉冲能量为2 . 6闪、峰值功率为glw的调q绿光输出。
