Semiconductor laser pumping of a continuous-wave Pr/sup 3+/:LiYF/sub 4/ laser emitting at several wavelengths

We report continuous-wave laser operation of Pr/sup 3+/:LiYF/sub 4/ at 639.7 nm, 607.3 nm, and 522.6 nm using a frequency-doubled optically pumped semiconductor laser as pump source. Furthermore, a red continuous-wave Pr/sup 3+/:LiYF/sub 4/ laser was realized under GaN laser diode pumping.
