ABSTRACT
We report on the crystal growth, spectroscopy and first laser operation of a novel double molybdate compound - TmKY(MoO4)2. This orthorhombic (sp. gr. Pbna) crystal exhibits strong anisotropy of the spectroscopic properties due to its layered structure. The maximum stimulated emission cross-section for the 3F4 â 3H6 transition is 2.70×10-20 cm2 at 1856nm with a bandwidth of >110â
nm (for E || b). The lifetime of the 3F4 state is 2.29â
ms. Crystalline films and plates (thickness down to 70 µm) of high optical quality are obtained by mechanical cleavage along the (100) plane. Continuous-wave diode-pumped laser operation is achieved in such thin films and plates yielding a maximum output power of 0.88 W at â¼1.9 µm with a slope efficiency of 65.8% and a linearly polarized laser output. Vibronic lasing is demonstrated at â¼2.06 µm. TmKY(MoO4)2 is promising for microchip and thin-disk lasers.
