Abstract
The growth of damage sites from micrometric to millimetric scales under high energy laser system conditions have herein been investigated. In this realm, a saturation of the surface growth followed by the rapid expansion of radial cracks has been observed. This observation contrasts with the previously reported exponential behavior1 (for pulse durations above 2 ns) and linear behavior (for pulse durations below 2 ns). The observation of the longitudinal damage structure coupled with fractal analysis has shown that these shifts in growth behavior seem to be correlated with changes in the damage morphology.
