Abstract :
We report a detailed study of time resolved self-defocusing in InSb at room temperature, using 3 μs long CO2 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 
of -0.11 cm2/MW at an incident intensity of 210 kW/cm2.
of -0.11 cm2/MW at an incident intensity of 210 kW/cm2.Keywords :
