Abstract
We report on the crystal growth spectroscopic investigations and laser experiments of thuliumdoped Lu2O3 Crystals with dopant concentrations between 02 at and 10 at were grown by the Nacken–Kyropoulos and the HeatExchanger 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 Tisapphire 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 15 W A continuous tuning range from 1900 nm to 2110 nm was obtained
