Abstract
We report on the crystal growth, spectroscopic investigations, and laser experiments of thulium-doped Lu2O3. Crystals with dopant concentrations between 0.2 at.% and 10 at.% were grown by the Nacken–Kyropoulos and the Heat-Exchanger Method. Absorption and emission spectra are presented, as well as the lifetimes of the energy levels involved in the laser process. The laser experiments were carried out using a Ti:sapphire laser emitting at 796 nm as the pump source, achieving a maximum slope efficiency of 68% with respect to the absorbed pump power and a maximum output power of 1.5 W. A continuous tuning range from 1900 nm to 2110 nm was obtained.
