Spectroscopic properties of Yb-doped scandium based compounds Yb:CaSc2O4, Yb:SrSc2O4 and Yb:Sc2SiO5

Abstract Three Yb3+-doped scandium based materials are elaborated and their optical properties investigated. Scandium materials exhibit large energy levels splitting and favorable thermal properties. The energy level diagrams for Yb:CaSc2O4, Yb:SrSc2O4, and Yb:Sc2SiO5 are determined through optical spectroscopic analysis and semi-empirical crystal-field calculations using the simple overlap model. Laser parameters for Yb:Sc2SiO5 are compared to Yb:Y2SiO5 ones. Yb:Sc2SiO5 looks promising since it melts congruently and exhibits larger overall splitting of the 2F7/2Yb3+ ground state and broader absorption line width.
