Abstract
A mercury cadmium telluride photoconducting detector has been irradiat ed with a carbon dioxide laser for a duration of 2-5 sec. The irradiat ion power densities are low enough and do not produce any permanent ch ange in the device. It is observed that the responsivity of the detect or decreases by two orders when it is irradiated by a power density of 20 W/cm(2). The results are correlated with temperature rise of the d evice.
