Effects of γ-Ray Irradiation on Optical Breakdown of KCl Single Crystal

Apodizing induced-absorption apertures with a large optical beam diameter and their application in high-power 1.06 μ laser systems

“…This was in agreement with the results reported in Ref. 9, where it was shown that the damage threshold of KBr crystals did not decrease because of the absorption induced as a result of action of γ rays.…”
