We report on the crystal growth, spectroscopy and first laser operation of a novel double molybdate compound -Tm:KY(MoO 4 ) 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 3 F 4 → 3 H 6 transition is 2.70×10 -20 cm 2 at 1856 nm with a bandwidth of >110 nm (for E || b). The lifetime of the 3 F 4 state is 2.29 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 ~1.9 μm with a slope efficiency of 65.8% and a linearly polarized laser output. Vibronic lasing is demonstrated at ~2.06 μm. Tm:KY(MoO 4 ) 2 is promising for microchip and thin-disk lasers.

“…[4] In fact, it was not until 2014 that the first laser action of Yb ion in orthophosphates was demonstrated with a Yb:LuPO 4 crystal plate. [5] Since then, progress has been made in growing miniature columnar crystals of Yb:LuPO 4 , as well as in studies of its continuous-wave (CW) and Q-switched laser performance. [6][7][8][9] Given the isomorphic crystal structures of LuPO 4 and LuVO 4 and the identical lattice site having a local symmetry of point group D 2d at which the Yb ion enters, it will be interesting and instructive to compare the lasing properties of Yb ion in these two host crystals in order to clarify how and to what extent the host crystal structure and ligand field (crystal field) can determine the basic lasing properties of an active ion.…”

A comprehensive investigation is carried out to compare the spectroscopic properties, absorption saturation behaviors and lasing properties of a Yb ion in tetragonal LuPO 4 and LuVO 4 isomorphic crystals. Significant distinctions are revealed in many aspects of the lasing behavior for the Yb ion doped in the two crystal hosts, and Yb:LuPO 4 proves to be superior to Yb:LuVO 4 since it enables efficient laser action to be much more easily achieved. With a 0.6 mm thick crystal plate of Yb:LuPO 4 , an output power of 3.30 W can be generated with an optical-optical conversion efficiency of 50.8%; whereas with a 2 mm long miniature crystal rod, the output power produced can reach 8.35 W with an optical-optical conversion efficiency of 46.7%.

“…Recently, we have grown single crystals of Yb:LuPO 4 employing high-temperature solution method, with largest dimensions amounting to 6 mm × 2 mm × 0.5 mm [6]. With these thin crystal plates, continuous-wave (CW) laser action was realized, generating an output power of 1.6 W [7]. Apart from such thin-plate shaped crystals, columnar crystals of Yb:LuPO 4 were also developed, from which miniature crystal rods could be prepared, and CW laser operation was realized with Yb:LuPO 4 miniature rod, showing a potential of generating 5-10 W of output power [8].…”

A diode pumped Yb:LuPO 4 miniature crystal rod laser operating at wavelengths of 1005.0-1012.5 nm, which was passively Q-switched with a Cr 4+ :YAG saturable absorber, was demonstrated. An average output power of 7.2 W at 1012.5 nm was generated at a pulse repetition rate of 166.7 kHz, with optical-to-optical and slope efficiencies being 38.5% and 45%, respectively. Under conditions of higher output coupling and lower initial transmission of the saturable absorber, an output power of 2.9 W at wavelengths around 1005.0 nm could be reached at 19.2 kHz, the resulting pulse energy, duration and peak power were respectively 151 µJ, 3.0 ns and 50.3 kW.
