Q-switched diode-pumped Yb:YAl3(BO3)4 lasers provide an average output power of 4.15 W, pulse energy of 139 muJ, pulse duration of 18 ns, and a slope efficiency of 59% operating near 1040 nm at room temperature.
Output power of 470 mW, slope efficiency of 64.5% and tunability between 1016 and 1049 nm are achieved with the novel disordered uniaxial crystal Yb:LiGd(MoO4)2. Both possible polarizations are compared and diode-pumping is also demonstrated.
Maximum output powers of 1.4 and 4 W and slope efficiencies of 60 and 69% were obtained with a Tm:KLu(WO4)2 laser near 2 mum under Ti:sapphire and diode laser pumping, respectively.
The generation of 12.4 W of output power with optical-to-optical conversion efficiency of 47% and slope efficiency of 74% is demonstrated in Yb:KGW laser end-pumped with high-power diode bars. Thermal-lensing and laser tuning has been investigated.
We demonstrate output powers exceeding 4 W with continuous-wave, diode-pumped Yb:TVO4 (T=Y, Gd, and Lu) lasers operated at room temperature. The three orthovanadate hosts are compared in longitudinal and thin-disk pump geometries.
