Paper Abstract

So called “fatigue effect” of optical materials is governed by distinct underlying physical processes, thus, it is sensitive to laser irradiation conditions, intrinsic material- and environmental-properties, is not always deterministic and therefore hardly predictable. There exist models that relate various pulse and material characteristics to predict fatigue, however many quantitative features of materials and scaling laws of irradiation for such models remain unknown. To address this appropriate experimental data is needed. Thus, fatigue of transparent material was quantitatively investigated by using time-resolved digital holographic microscopy. Various dependencies were investigated by changing pump irradiation conditions as a function of incident pulses.
