Abstract:

The results of a number of experiments are presented which were aimed at detailed characterization of the spatial profile of the laser beam both before and after amplification. Revised values of previous damage thresholds are presented as well as the results of measurements of damage threshold as a function of lens focal length. In other experiments, the time evolution of the damage tracks in ruby and sapphire was studied using a fast streaking camera. Because of the importance of self-focusing considerations in damage studies, a detailed derivation of theoretical results reported recently by other workers is presented as an appendix.
