摘要

The results of investigations of the influence of gamma and proton radiations on absorption, luminescence and birefringence of either pure or Cu, Fe and Cr doped LiNbO_3 single crystals were presented. A method of birefringence dispersion testing on the entire areas of plane-parallel plates of LiNbO_3 crystals ahs been illustrated by the influence of both types of irradiation on Pure and Fe, Cr and Cu-doped LiNbO_3 wafers. It was found that LN:Cu single crystal shows different behavior to the other investigated crystal. First of all it exhibits lower susceptibility to #gamma#-rays, the absence of 500 nm additional absorption, and strong proton susceptibility observed in polarimeter measurements.
