Abstract
We report bolometric photoresponse of YBa2Cu3O7-x thin film and YBa2Cu3O7- x/La2CuO4 multilayers at temperature of liquid nitrogen irradiated by a semiconductor laser diode at 0.83 microns. We develop a heat transfer model which takes into account the lateral diffusion of heat in the substrates. Using this model we explain the time dependence of the photoresponse. From the analysis of the photoresponse voltage versus time we calculate the optical absorption of the YBa2Cu3O7- x/La2CuO4 multilayers and of the YbaCuO monolayer.
