The influences of the characteristics of pulsed laser source and cfpi on the accuracy of detedtions are analysed in detail 通过对超声振动位移与激光脉冲的光功率密度的关系进行分析,发现二者之间存在正比关系。
The laser damage threshold of the ybyp _ xv _ ( 1 - x ) o _ 4determined by nd : yag laser , which showed a decreasing tendency with the increase of the dopant concentration 利用nd : yag激光器测试晶体的激光损伤阈值,随着掺杂离子浓度的增大,激光损伤光功率密度呈减小趋势。
In fact , as the fiber has the character of special low loss and small size of effective area , high light power density can be achieved in the fiber through low incident light power , which result in nonlinear effects affecting the operation of the system 实际中由于光纤具有极低的损耗以及很小的光斑尺寸,使得只需较小的注入光功率即可在光纤内获得较高的光功率密度,从而产生影响系统有效工作的非线性效应。
