      Computational models of the intense laser radiation interaction with photodetector arrays based on InSb and CdxHg1-xTe with substrate layers made of Si, GaAs, Ge, and InAs to determine their effect on the generation and evolution of emerging thermal fields have been developed and implemented in the "Logos" engineering analysis and computer simulation software package. Temperature dependences were examined and represented in their analytical form for optical and thermophysical parameters of materials under consideration. Simulation results, which have been analyzed and generalized, are presented.
