探测束非聚焦CW交叉束热透镜的理论分析

Theoretical analysis for CW crossed-beam thermal lens with unfocused probe beam

本文基于把样品池当作薄位相板,运用傅里叶光学理论,对探测束非聚焦CW双束正交热透镜构型进行了理论分析,预示了由此构型产生的热透镜特性。

Taking the sample cell as a thin phase plate and utilizing Fourier optica theory, a theoretical analysis for CW crossed-beam thermal lens with unfocused probe beam was proposed. Also obtained are group of the characteristic curves describing thermal lens properties, which are in agreement with experimental results.
