摘要
本文分析了高强度激光斜入射时等离子体共振吸收对光声信号的影响 ,导出了等离子体共振吸收最强时激光入射角的表达式 ,得出了激光斜入射时 ,随着激光入射角的增大 ,光声信号会出现一个极大值 ,并通过实验进行了验证。
The paper deals with the effect of resonant absorption of plasmas on photoacoustic signals in the case of laser incidence.The formula of the angle of laser incident in the case of maximum of plasma resonant absorption is derived.There is maximum of photoacoustic signal with the increase of the angle of laser incident,which have been tested by experiments.
