Abstract

We report on crystal growth, spectroscopic investigations, crystal field tuning, and laser experiments of neodymium doped mixed sesquioxides (Lu1−xScx)2O3. Crystals were grown by the Nacken–Kyropoulos and the Heat-Exchanger method. Emission spectra for several mixing ratios are presented. Cw laser experiments were carried out with a 0.35 at.%-doped Nd:Lu1.82Sc0.18O3 crystal by using a Ti:sapphire laser as pump source, achieving a maximum slope efficiency of 47 % with respect to the absorbed pump power and a maximum output power of 356 mW at a wavelength of 952.7 nm. To the best of our knowledge, this represents the first continous wave (cw) laser operation of a Nd-doped mixed sesquioxide.
