Paper Abstract

Using the results of previous experiments, CO2 laser induced impact ionization in InSb has been evaluated using measured dc ionization rate data. The laser field is scaled by 1/w'r, where o is the laser frequency and t is the momentum relaxation time of the hot electrons. Scaling is done to provide an ionization rate consistent with the experimental conditions. In this way, a momentum relaxation time t, 0.34 p5 can be deduced, in agreement with the value previously determined by four wave mixing experiments.
