Abstract
We investigated the 1443.9nm laser characteristics of Nd:GdLuAG crystal. Diode-end-pumping configuration was employed under both continuous-wave (CW) and passively Q-switched operations. For CW operation, the maximum average output power was 1.36W with a slope efficiency of 15%. By using a V3+:YAG crystal as the saturable absorber, we obtained the maximum average output power of 164mW under Q-switched operation. The corresponding pulse energy was 29.3μJ and pulse duration was 59ns.
