Laser Produced Damage in Transparent Solids

Abstract

The mechanism governing the onset of laser-produced damage in solids was found to depend, in a critical way, on the spatial and/or temporal gradient of the interaction strength across the focal or volume. As a result, the threshold values of damage produced by a multimode laser as well as the internal damage patterns depend strongly on the laser propagation and polarization directions. In the forward scattering experiment, the cumulative effects of microscopic damage were observed in crystalline quartz. Other experiments designed to detect cumulative effects were inconclusive. Various light scattering spectroscopy as a diagnostic tool for laser-produced damage studies were investigated.
