Results of experiments on laser hardening of various materials with intensity 109~1010 W/cm2 are represented. Nd∶glass laser with energy up to 45J with a pulse duration ~30ns was used as a source of radiation. Comparative researches of the laser peening for the various target areas are fulfilled. Results of laser hardening were determined by the microstructure analysis. The new approach to creation of the industrial laser for peening is discussed.
