Paper Abstract

We report on the results of lasing and spectroscopic investigations of the anomalously slow recoverable bleaching of Cr,Ca:YAG and Cr,Mg:YAG crystals. We propose two models for this effect: (i) Cr4+ reduction to Cr3+ due to oxygen valence band electron capture by Cr4+, and (ii) induced disorder in Cr4+ tetrahedral center due to effect of oxygen vacancies.
