Efficient diode-pumped Er:KLu(WO4)2 laser at similar to 1.61 mu m
Original language description
We report on an efficient diode-pumped continuous-wave erbium-doped monoclinic double tungstate laser. It is based on a 1 at.%Er3 :KLu WO4 2 (Er:KLuW) crystal cut along the Ng optical indicatrix axis. The Er:KLuW microchip laser, diode pumped at 0.98 μm, generates 268 mW at 1.610 μm with a slope efficiency of 30%. The output is linearly polarized (EjjNm), and the laser beam is nearly diffraction limited (M2p, m < 1.1). Spectroscopic properties of Er3 in KLuW are also presented. The stimulated-emission cross-section σSE is 0.46 × 10−20 cm2 at ∼1.609 μm for EjjNm. The microchip Er:KLuW laser outperforms the commercial Er,Yb:glass.
