确定了在入射激光脉冲作用期间，染料介质折射率增量随时间的变化近似取半立方抛物线形式，并确认光-热效应对折射率变化的贡献在本实验条件下是最主要的。
Finally it is confirmed that in the duration of input laser pulse the refractive-index variation increases with time approximately in the form of semi-cubic parabola , and the main mechanism to cause this variation is the opto-thermal effect of the sample medium .
