Résumé
We report on spectroscopic investigations of the mixed sesquioxide laser materials Yb:LuScO<sub>3</sub>, Yb:YScO<sub>3</sub>, and Yb:(Lu,Y,Sc)<sub>2</sub>O<sub>3</sub> as well as mode-locked thin disk laser experiments with Yb:LuScO<sub>3</sub> and Yb:(Lu,Y,Sc)<sub>2</sub>O<sub>3</sub>. The disordered crystal structures of these materials result in significantly broader emission spectra than for the pure sesquioxides Yb:Sc<sub>2</sub>O<sub>3</sub>, Yb:Y<sub>2</sub>O<sub>3</sub>, and Yb:Lu<sub>2</sub>O<sub>3</sub> providing a high potential for ultrashort pulse generation. In SESAM mode-locked thin disk laser experiments, pulse durations of around 100 fs could be obtained exploiting >70 % of the gain bandwidth which is to the best of our knowledge the optimum obtained so far for the mode-locked lasers in this setup.
