Abstract

The proliferation of optical elements in systems that are subject to harsh ionizing radiation environments prompts the need for commercially available radiation-hard materials, such as laser materials. In the present study, changes in the material optical absorption are compared for a suite of single-crystal YAG, Nd 3+ YAG, and Cr 3+, Nd 3+ : YAG laser materials in response to high-dose-rate gamma radiation events. It is found that the addition of Cr 3+ yields radiation hardened material.
