Abstract

Scheelite-like disordered double sodium-lanthanum molybdate NaLa(MoO₄)₂ single crystals co-doped with Er³⁺ and different concentrations of Ce³⁺ have been grown by Czochralski technique. The 300K spectroscopic properties of the excited states ⁴S_3/2, ⁴I_11/2 and ⁴I_13/2 of Er³⁺ ions in grown crystals as a function of Cerium concentration have been investigated. The lifetime of ⁴I_11/2 have been found to reduce from 130 μs in the solely Er-doped sample to approximately 3.5 μs, when the concentration of Ce reaches 50 at. %. At the same time the lifetime of ⁴I_13/2 level at 300 K remains unchanged (3.7 ms) up to the concentration of Ce in crystal equal to 10 at. %, and reduces by less than 30% (2.6 ms) in the 50 at. % Ce co-doped sample. This result looks very promising from point of view of obtaining low-threshold 1.5 μm laser oscillation.
