PULSE-PROPAGATION EFFECTS IN BULK INSB CRYSTAL

Based upon the time dependent perturbation technique for coherent ultr afast pulsed radiation-semiconductor interaction, the transient induce d polarization has been considered for the analysis of change in the p ulse shape while propagating through the material. Using the electroma gnetic treatment, the output held amplitude is obtained. Numerical est imations are made for a sample of InSb crystal duly irradiated by lead -salt (PbEuSeTe) diode laser operating in the 2.6-6.6 mu m wavelength range. The analytical results are in very good agreement with the avai lable experimental and theoretical results. Copyright (C) 1997 Publish ed by Elsevier Science Ltd
