Study on Relaxation Process of Thermal Eeffect Using Two-Color Z-SCAN Technique

用双色Z－SCAN法研究了热效应的弛豫过程，首次给出了为得到最大的测量灵敏度所满足的泵浦光束和参考光束的几何条件．在实验上对偶氮染料有机物热弛豫时间进行了测量。

We have analyzed the two-color ZSCAN technique to study relaxation process of thermal effect. By means of Gaussian decomposition method, the experimental condition for maximum measuring sensitivity has been derived, and the thermal relaxation time of azobenzene compounds measured, too.
