Abstract

The theoretical treatment of laser-induced damage to optical materials has in the past been largely based upon phenomenological observations, empirical treatments and the non-linear effective medium approximation. In some instances such as intrinsic damage thresholds, these approaches show merit. In many other cases, such as those related to contamination, laser optical damage, specific treatment of both matter and energy is required. The base assumptions of some of the more common theories of laser material interactions are discussed and their effects upon the predicted behavior identified. While this paper does not provide a quantitative solution to the issue of laser damage thresholds, it provides physically sound descriptions of interactions and points the way to potential solutions.
