Abstract
LuLiF4 single crystals co-doped with thulium (5%) and holmium (0.5%), which had large size, intact shape and high optical quality, were successfully grown by the medium frequency induction heating Czochralski Technique. The absorption spectrum of the crystals showed that the main absorption peak located at 686 nm and 792nm. At room temperature, LuLiF4 single crystals co-doped with thulium (5%) and holmium (0.5%) were end-pumped by a fiber-coupled laser diode system with pumping wavelength of 795 nm. We achieved power of 50 mw continuous laser output at 2.05 μm wavelength.
