Abstract

Light transmission in a type-II photon avalanche model based on interband transitions in crystals is studied. For various laser radiation durations and different material thicknesses, the transmission dependences on the intensity of the incident light j0 are obtained. It is shown that the transmission decreases sharply with increasing j0. Thus, in the nanosecond time range, an effective attenuation of radiation with j0≈30–150  kW/cm2 at lengths of 10−2–10−1 cm can be obtained.
