Paper Abstract

The analysis of the under-threshold phenomena in the surface layer of the lithium niobate under intense laser irradiation was carried out. The accumulation effect leading to the laser damage was considered in the framework of the influence of the particle emission from the investigated sample surface on the electronic processes in the surface layer. The model of the oxygen depletion of the surface due to the intense nanosecond laser pulses is suggested. The influence of the absorbed surface layer on this process is considered. This model is in agreement with the experimental data of the laser damage threshold dependence on the oxidizing/reduction properties of the environment.
