The paper studies the initiated damage morphology and the subsequent damage growth on fused silicas exit-surface and input-surface in air under nanosecond laser irradiation at 1 064 nm and 532 nm. The results demonstrate a significant dependence of the initiated damage on laser parameters and surface defects characters, and of the damage growth on the laser wavelength, location and fluence. Exponential growth behavior appears for exit-surface and linear growth one for input-surface in the lateral side of the damage site with the increase of shot number. Possible reasons for the observed initiated damages and damage growth behaviors are discussed.
