Abstract

Chromium-doped crystals of the Colquiriite class materials have received much attention since first reported in 1988. The crystal that has got the least attention of these is the LiSGaF mainly because of lack of availability. The limited information available indicates that at least some of the properties of this crystal might be superior to those of the other Colquiriite crystals. In particular the thermal expansion of LiSGaF is both lower and more isotropic than that of the others and the passive losses, including scatter losses, are much lower.¹
