  • We report on crystal growth, spectroscopic investigations, crystal field tuning, and laser experiments of neodymium doped mixed sesquioxides (Lu 1-xSc x) 2O 3. 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:Lu 1.82Sc 0.18O 3 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 356mW 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. © Springer-Verlag 2012.
