    Abstract

    Recent work by Jones et al. and Shen et al. established the detailed intrinsic damage mechanisms in NaCl and KBr exposed to short laser pulses at 532 nm. Predictions of the dependence on experimental and material parameters of energy deposition from the laser pulse to the wide-gap optical solid can now be made with confidence. We examine the effects of initial temperature and of pulse length on the damage threshold. We also discuss the role of defect accumulation in multiple shot damage in KBr.
