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