Paper Abstract

A Sr 3 Yb 0.1 Gd 0.2 Y 0.7 ( BO 3 ) 3 single crystal was grown by the Czochralski method. The crystal was evaluated by absorption, emission, and luminescence decay measurements. The relevant absorption and emission cross-sections as well as fluorescence lifetimes were calculated and compared. Studies showed that the existence of Gd 3 + can lead to greater structural disorder and broaden the spectra of the crystal. Diode-pumped laser action of this crystal is demonstrated for the first time, and the best output power of 1.8 W with a slope efficiency of 75.8% was obtained. Dual-wavelength and three-wavelength oscillations were observed. Thus, this crystal is suitable for use as tunable or ultrashort laser mediums.
