Damage morphologies on lanthanum doped lead zirconate titanate (PLZT) surface induced by nanosecond and femtosecond pulses irradiate. Different levels of the high power nanosecond and femtosecond pulses are irradiation on the surface of PLZT, where the pulses are near Gaussian beams. The damage probability is observed on line and the suitable powers of the pulses are adjusted. The nanosecond pulse induced damage threshold of PLZT is 485 MW/cm2. The variations of the damage spot diameters versus the energy irradiation are analyzed. The variation of the damage depth versus the damage diameters and the damage morphology induced in the defect in the ceramic are also detected and recorded. The damage morphologies induced by nanosecond and femtosecond pulses are also contrasted. And some possible explanations due to the difference are given.
