%X In the article the results of analyze of laser ultrasound generation in inhomogeneous semiconductors plate is presented. The case of strong absorption of electromagnetic fields is considered. It is shown that in this case submicron surface layer thermal properties influence on thermal distribution evolution. The case of thin infinite plate considered. Peculiarities of excitation and propagation of elastic waves in such media regarding gives the possibility to obtain dispersive equation for laser ultrasound wave-vectors. It is shown that such processes in 1D case can be described.
