Abstract
The optical spectroscopy of an ytterbium-doped multicomponent alkaline earth metal fluoride crystal Yb3+,Y3+:(Ca,Sr)F2 was studied with the goal of developing novel gain media for ultrafast mode-locked oscillators. The contribution of phonon-assisted (Stokes) emission to extending the gain profile beyond the range of electronic transitions was evidenced.
