Abstract

Investigations on the electrical transport properties of dielectric garnets used for laser and optical device applications are reviewed. Electrical conductivity studies of YAG (Y3A15012), GSGG (Gd3Sc2Ga3012), and CALGAR (Ca3Al2Ge3012) are interpreted in terms of possible point defecE models and correlated, where possible, with spectroscopic investigations of optically deleterious point defects. The defect chemistry and electrical properties of insulating garnets are compared with results of previous studies on highly conducting magnetic garnets. The ability of electrical conductivity experiments to assist in the understanding of the defect structure of optical and laser garnets is demonstrated, with particular focus on the behavior of color centers and anomalous absorption in garnets at high temperature and in controlled atmospheres.
