Thermo-Elastic Action of the Powerful High Pepetition Rate Laser Radiations on the Solid State Surface

The phenomena of the thermoelastic behavior of materials under powerful, high-repetition-rate laser radiation are discussed. An analysis is based on the Duamel integrals for the therms-stress characteristics which correspond to CW and high-repetition-rate laser irradiations. Relationships for the upper-level laser intensities which are connected with admissible elastic surface distortion, plastic flow of the material, fatigue distributions, and melting of the surface layer are calculated.
