The results of studying the influence of laser pulse irradiation on the structure of the zirconium alloys surface layers are presented. As a result of laser irradiation of the alloys surface the multyscalihg structure which included large-scale and small-scale changes of surface relief was formed. Under laser pulse irradiation of alloys surface the concentration of intermetallic phase’s inclusions in the surface layer to a depth of 0.3 μm of ageing alloys was reduced. Due to the rapid heating and solidification of a liquid melt the front of the melt is moving at high velocity and accelerated migration of inclusions into the surface layer of the irradiated spot.
