Abstract
Laser diode pumping changes the whole thinking of solid state laser design. To achieve maximum efficiency, it is necessary to optimize material properties of laser hosts. Fluorides, in general, perform well under diode pumping. To further enhance the efficiency, we conclude that high optical anisotropy is desirable. Based on this criteria, we report here our investigation of three new laser host crystals, KYF4, LiGdF4 and KLiYF5. None of these compounds melt congruently, nevertheless, we are able to grow them based on peritectic curves using conventional Czochralski pulling equipment with automatic diameter control. Spectroscopic and lasing results of these crystals are also presented.
