Abstract: Crystal with composition Li2Zn2(MoO4)3 doped with 0.7 at.% Yb (Yb:LiZnMo), with high optical quality and few cm long is grown from the flux using Li2MoO4 as a solvent. Yb:LiZnMo is orthorombic (sp. gr. Pnma, a = 5.0843 Å, b = 10.4927 Å, c = 17.6742 Å, Z = 4). Polarized Raman spectra are studied for this crystal; the most intense band is observed at 898 cm-1. The ab-sorption, stimulated-emission and gain cross-sections of Yb3+ ions are deter-mined for the principal light polarizations, E || a, b, c. The maximum ¿SE = 6.6×10-21 cm2 at 1011 nm for E || b. The gain bandwidth for Yb:LiZnMo is up to ~50 nm. The radiative lifetime of the Yb3+ ions is 1.55 ms. The Yb:LiZnMo crystals are very promising for broadly tunable lasers.
