Abstract

Cokquirite type crystals have the genera1 formula LiMe^IIMe^IIIF₆ and received their name from the mineral LiCaAlF₆ that was found in the Bolivian tin mine Colquiri. Amoung the colquiriites especially LiCaAlF₆ (LiCAF), LiSrAlF₆ (LiSAF) and. more recently, LiSrGaF₆ (LiSGaF) are considered to be interesting laser host crystals for chromium and cerium doping Single crystals are grown from the melt by the bridgman or czochralski methods and exhibit homogeneous doping, as the distribution coefficient $k_{\text{eff}}=c_{\text{solid}}^{{\text{Cr}}^{3+}}/c_{\text{liquid}}^{{\text{Cr}}^{3+}}$ is close to unity
