Abstract

An Er:Yb:Ba3Gd(PO4)3 crystal was grown by the Czochralski method. Spectral properties of the crystal associated with 1.5–1.6 µm laser operation were investigated, including the absorption and fluorescence spectra and the fluorescence decay at room temperature. The fluorescence quantum efficiency of the 4I13/2 level of Er3+ ions and energy transfer efficiency from Yb3+ to Er3+ ions were calculated. A CW diode-pumped Er:Yb:Ba3Gd(PO4)3 laser at 1.5–1.6 µm with output power of about 73.9 mW and slope efficiency of 16.3% was achieved for the first time in the Er3+/Yb3+ co-doped phosphate crystal.
