Abstract:
At room temperature, highly efficient, doubly resonant periodically poled MgO-doped congruent LiNbO3 crystal optical parametric oscillators (OPO) pumped at 1.9 μm have been realized for the first time to our knowledge. A 2.9 W, 2 kHz acousto-optic Q-switched homemade Tm:YLF laser served as a pump source. A 900 mW mid-infrared emission generated from an OPO is illustrated. The overall mid-infrared generation conversion efficiency reached 31%, whereas the slope efficiency was up to 70%.
