%X In the present article we want to consider some features of not thermal influence of laser pulses on multilayer heterogeneous nanofilms to present the results of our experimental researches of change of the roughness of a surface and magnetic characteristics of permalloy films after their irradiation nanosecond laser pulses and the results of measurement of dynamics of magnetic reversal of magnetic tunnel nanostructures with one and two magnetic nanolayers. It is shown that the photon drag effect of electrons can not only generate an electric potential difference between the input and output surfaces in a semiconductor, but may also lead to a drift of the impurities. The results of our research show that in the thin CdS single crystals can be obtained stimulated emission of electromagnetic radiation in the terahertz frequency range.
