saturable absorber meaning in Chinese
可饱和吸收器
选择性饱和滤光器非线性滤光器
Examples
- Effect of saturable absorber to solid state mode - locked femtescond laser
饱和吸收体对飞秒脉冲固体激光锁模的影响 - Semiconductor saturable absorber mirror mode - locked optically pumped vertical - external - cavity surface - emitting semiconductor lasers
半导体可饱和吸收镜锁模光抽运垂直外腔面发射半导体激光器 - In low laser intensity , cr4 + : yag can be used as slow saturable absorber . the nearer is the initial transparence to the max initial transparence , the bigger is the loss modulation
在光强不太大的情况下， cr ~ ( 4 + ) yag可作为慢饱和吸收体，其初始透过率越靠近最大初始透过率，损耗调制越大。 - Particularly , cr4 + - doped crystals as passive q - switch ( saturable absorber ) have got extensive attention , such as cr4 + : yag ， cr4 + : gsgg ， cr4 + : mg2sio4 and cr4 + : yso , which have the advantages of wild absorption band , good saturable absorption , long restored time , good photo - chemical stability , no fading , good thermal conductivity and high damage threshold
特别是近年来，掺cr4 +离子的各种晶体如cr4 + : yag ， cr4 + : gsgg ， cr4 + : mg2sio4和cr4 + : yso等作为被动调q开关受到了广泛的关注。它们具有很宽的吸收带和良好的饱和吸收性质，恢复时间较长，光化学性质稳定，无退化现象，热导性好，损伤阈值高。 - 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。
