The change in the crystal structure of a number of metals 
(Cu, Al, Ag) under laser radiation of power density 104 - 105 W/cm2 
was detected by the method of x-ray diffractometry. It was 
suggested that this effect is due to the large microstresses 
arising in the zone of rapid anisotropic heating of the 
metal under irradiation.
