Abstract

The disordered crystal ${LiGd}_{0.936} {Yb}_{0.064} ({MoO}_{4})_{2}$ was grown with high optical quality by the flux method using ${Li}_{2} {MoO}_{4}$ as a solvent. The crystal possesses tetragonal symmetry belonging to the space group $I \bar{4}$ , with two nonequivalent sites occupied by the dopant. Spectroscopic studies at 5 and $300 K$ provided information on the Stark energy-level splitting and the absorption and emission cross sections of the ${Yb}^{3 +}$ ion. Laser operation of ${Yb}^{3 +}$ was obtained for the first time in such a Li-containing double tungstate or molybdate. The tuning range with a Ti:sapphire laser pumping extended over $\sim 32 nm$ for the σ polarization and $23 nm$ for the π polarization. Without a tuning element the laser performance was similar for the two polarizations. By using a 10% transmission output coupler, a maximum output power of $\approx 470 mW$ was obtained with a slope efficiency $η = 64.5 %$ and the absorbed pump power at threshold was $520 mW$ . Laser operation was also achieved by pumping with a tapered diode laser and a fiber-coupled diode laser module, with a Yb laser output power of $0.66 W$ in the latter case.
