Analyses show that refractive index changeinduced by thermal effect is similar to the change induced by other effects for linearabsorption,if laser pulse width is far less than the characteristic time of sample,i.e.refractive index change is directly proportional to spatial part of incident pulse laserintensity,so time averaged nonlinear refractive index can be defined.

结果表明，当激光脉冲宽度远小于被测样品的特征时间时，对于线性吸收来说，其热效应产生的折射率变化与其它效应产生的折射率变化有类似的形式，即与入射脉冲激光光强的空间部分成正比。因而可定义时间平均非线性折射率。在这种情况下，可用通常的Z-scan法进行非线性折射率及热光系数的测量，所得结论符合以前的实验结果。
