The surface damage caused by laser irradiation is studied to investigate the possibility of performing a depth-profile analysis of the hydrogen concentration in zircaloy-4 alloys using laser-induced plasma breakdown spectrometry. After laser irradiation, a heat-affected zone extending about 3 {mu}m down from the top surface can be seen. The depth of this heat-affected zone is independent of the laser power density in the range 10{sup 8} to 10{sup 9} W/cm{sup 2}. In order to obtain the depth profile of the hydrogen concentration in zircaloy-4 alloys, the power density of laser shots must be greater than 1.3x10{sup 9} W/cm{sup 2}.
