用3 μs长的CO2激光脉冲，对室温下InSb晶体的时间分辨自散焦进行了详细的研究。我们已经确定，折射率的强度依赖性随强度的三分之二次方而变化。测量值对应于在210 kW/cm 2的入射强度下-0.11 cm 2/MW的等效dn/dI。
We report a detailed study of time resolved self-defocusing in InSb at room temperature, using 3 μs long CO 2 laser pulses. We have determined that the intensity dependence of the refractive index varies as intensity to the two-thirds power. The measured values correspond to an equivalent dn/dI of -0.11 cm2/MW at an incident intensity of 210 kW/cm2.
