Paper Abstract

The properties of laser using Er:YLiF4 and Er:YVO4 crystals at approximately 1.6 micrometer wavelength are studied by equations deduced from speed equations. The results indicate that the laser threshold energies of Er:YLiF4 and Er:YVO4 are 4.4 and 2.0 times respectively lower than that of Er:YAG. The slope efficiencies of Er:YLiF4 and Er:YVO4 crystals are 3.7 and 1.5 times higher respectively than that of Er:YAG crystal. Therefore the YVO4, especially the YLiF4 crystal is a fine host crystal doped Er3+ ions, whose threshold is low and slope efficiency is high.
