Abstract
Trivalent thulium-doped single crystals have been grown by the Czochralski method. Room-temperature polarized absorption and fluorescence spectra of the crystals were analyzed. The fluorescence decay curves of the , , and multiplets were measured, and the decay mechanisms of the and multiplets were discussed. Spectroscopic parameters related to the laser operation around via the transition have been evaluated. Finally, end-pumped by a Ti:sapphire laser at 795 nm, the room-temperature quasi-continuous wave laser emission was demonstrated with a slope efficiency of 28%.
