Paper Abstract

Application of the metallic thin-film selector to tunable, single frequency oscillation of diode pumped lasers has been investigated theoretically and experimentally. Tunable, single frequency output was achieved in Nd:YAG, Nd:YVO4 and Nd:YLF crystals. The best results were obtained in case of Nd:YVO4 crystal namely up to 0.6 W output power for 2 W pumping laser diode with optical slope efficiency > 40 percent. Single frequency operation, slow smooth tuning or chirping within range 0.5-10 GHz was realized by means of output coupler movement with the piezoceramic transducer. In case of Nd:YLF crystal single frequency generation on both 1047 nm and 1053 nm lines was accomplished. Physical and technical limitations caused by the wide gain bandwidth, thermal effects and mechanical vibrations of cavity elements were discussed.
