Description

Crystal with composition Li2Zn2(MoO4)3 doped with 0.7 at.% Yb (Yb:LiZnMo), with high optical quality and a length of a few cm 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 absorption, stimulated-emission and gain cross-sections of Yb3+ ions are determined for the principal light polarizations, E || a , b , c . The maximum σ 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. (letter)
