Abstract

Single crystals of gadolinium scandium gallium garnet (GSGG) doped with Cr and co-doped with Ca have been grown using the laser-heated pedestal growth method. This material emits in an eyesafe region of the spectrum, making it a potential candidate for use as an active medium in solid state lasers for a number of applications. Samples with various concentrations of chromium were prepared and analyzed using several characterization techniques. It was found that optical spectroscopy alone is not sufficient to discriminate accurately between the (CrO₄)^4- or the (Cr04)3- oxyanion centers which are formed when Cr⁴⁺ or Cr⁵⁺ substitutes for Ga³⁺ in the tetrahedral sites.
