摘要: We report on the first diode-pumped laser operation of thulium-doped Lu2O3. With a very compact setup an output power 75 W and slope efficiencies around 40% with respect to incident pump were achieved at room temperature. Free running was observed wavelengths 2065 nm 1965 nm. birefringent filter wavelength could continuously be tuned from 1922 nm 2134 nm. The thermal conductivity Tm:Lu2O3 measured for different dopant concentrations is compared one YAG.
