Abstract
If the researcher sample will be irradiate a powerful laser radiation, as a result of part of radiation will be absorbed, and the thermal fields appears there, the spatial-temporal distributing of which depends both on the parameters of laser radiation and descriptions of material of sample. The local increase the temperature of sample results to the different sort of the photostimulated changes in it and environment: thermodeformation of surface, infrared emission, thermal lens in sample and air, acoustic wave and others. In works [1 4] we are developed the photothermal methods of diagnostics of optical and thermophysical descriptions of materials after the experimentally registered thermal fields or deformation fields which appears at the irradiation the researcher sample by the powerful laser radiation beam with the known spatial-temporal distributing of radiation.
