Abstract

Dynamics of phase transitions induced by nanosecond laser pulses in cadmium zinc telluride wafers were studied with the time-resolved reflectivity method to determine basic thermodynamic parameters and chemical changes as a function of applied pulses and their energy density. The reflectivity spectra were recorded for the energy density range 140 - 3400mJ.cm^-2. Chemical decomposition of the CdZnTe alloy appears at the threshold energy density about 300 mJ.cm^-2 and this decomposition shifts transparency of the CdZnTe to the visible light.
