Paper Abstract

Developing large laser grade cubic rare-earth sesquioxides (RE2O3, RE=Y,Sc,Lu) single crystals doped with Yb3+ ions stands as one of the most challenging endeavours of today's crystal growth1,2. Recent studies on cubic RE2O3 single crystals have demonstrated their laser potential and highlighted the extreme thermodynamic conditions in which their growth takes place1-3. In particular, the laser performances of Lu2O3:Yb3+ crystals make them likely to outperform betterknown rivals such as YAG:Yb3+ or KY(WO4)2:Yb3+ for 976 nm diode-pumped systems4. Several mm3-sized Yb3+-doped Y2O3, Gd2O3 and Lu2O3 single crystals were recently grown by a newly designed high-temperature solution growth method5, and characterized by means of X-ray diffraction, Fourier transformed infrared (FTIR) spectroscopy and electron probe microanalysis (EPMA). Spectroscopic characterizations (absorption and emission cross sections, visible anti-Stokes emission, fluorescence decays) of these new cubic RE2O3:Yb3+ (RE=Y,Lu) single crystals are presented.
