Because of their fine extinction ratio and high anti-light-damage threshold value, laser-polarizing prisms are popular among workers in science and technology field. 激光偏光棱镜，以其优良的消光比性能和高抗光损伤阈值性能，备受科技工作者欢迎。
The referenced expression of damage threshold fluence in laser induced detector damage is given, also the obvious and recessive damage factors and their causes are analyzed. 摘要给出了光电探测器激光能量损伤阈值的参考表达式，并对导致激光损伤的显性和隐性因素及其成因进行了分析。
