CW and tunable laser operation of Yb~(3+) doped CaF_2

摘要

We present the spectroscopic properties and room temperature of a cw tunable laser operation with Yb~(3+) doped CaF_2 single crystals grown in our laboratory. A laser slope efficiency of 50% with respect to the absorbed 920 nm pump power was obtained, and the laser wavelength could be tuned between 1000 and 1060 nm.
