The experiments of high peak pulsed laser-induced damage to fused-silica fibers have been carried out. The experimental results show that all the damage sites accrued on the fiber end-faces. The morphologies of damaged fiber end faces are observed and recorded using metallurgical microscope. Micrographs of fiber end faces are processed using a Matlab program; the distribution characterizations of damaged sites on fiber end faces are obtained. According to the computing results, we find that the damage sites distribution obey certain regularities, which are different between on the input end faces and on the output end faces; The sizes of damaged sites obey normal distribution; The location distribution of damaged sites is strongly related to input or output laser characterization; The morphologies of damaged fiber end faces are strongly related to the mechanism of laser-induce damaged to fiber end faces.
