Abstract

We report bolometric photoresponse of YBa₂Cu₃O_7-x thin film and YBa₂Cu₃O_{7- 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 YBa₂Cu₃O_{7- x}/La₂CuO₄ multilayers and of the YbaCuO monolayer.
