| Abstract: | We report a detailed study of time resolved self-defocusing in InSb at room temperature, using 3 μs long CO2laser 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 equivalentdn/dIof -0.11 cm2/MW at an incident intensity of 210 kW/cm2. |
