The authors report bolometric photoresponse of YBa{sub 2}Cu{sub 3}O{sub 7{minus}x} thin film and YBa{sub 2}Cu{sub 3}O{sub 7{minus}x}/La{sub 2}CuO{sub 4} multilayers (YBCO/LCO) at temperature of liquid nitrogen irradiated by a semiconductor laser diode at 0.83 microns. They, develop a heat transfer model which takes into account the lateral diffusion of heat in the substrate. Using this model they explain the time dependence of the photoresponse. From the analysis of the photoresponse voltage versus time they calculate the optical absorption of the YBa{sub 2}Cu{sub 3}O{sub 7{minus}x}/La{sub 2}CuO{sub 4} multilayers and of the YBaCuO monolayer.
