查询词典 laser

There are two important mechanisms for increasing laser power afteradding hydrogen:(1)The gas temperature and CuBr vapor density at the center of lasertube are reduced, it decreases collision energy depletion of electron and leads to increaseelectron temprature;(2)Electron density increases during the pulse, the skin effect andthe" black center" of laser are improved.

同时，脉冲期间的电子密度增加，电子密度的趋肤效应减弱，激光的&黑心&现象被改善。2存在一个最佳充氢范围，其原因是：充氢后，随着气体温度的进一步降低，电子温度和铜原子数密度也将下降，它们与使电子温度升高的因素相互制约，抑制了激光能级粒子数的增长。
