摘要：
Experimental results of a high-efficiency 2.7 μm tunable laser are demonstrated on a quasi-phase-matched singly resonant optical parametric oscillator (OPO) in PPMgO:CLN (5% MgO-doping) crystal pumped by a 1064 nm laser. Theoretical analysis of the PPMgO:CLN temperature tuning is presented. When the crystal is operated at 150°C and the pump power is 182 W with a repetition rate of 10 kHz, an average output power of 36.7 W at 2.73 μm is obtained with a slope efficiency of 23.7%. The wavelength tunability of 3.0~2.6 μm can be achieved by adjusting the temperature of a 31.3 μm period PPMgO:CLN crystal from 30°C to 200°C. Compared with the results of theoretical analysis, the discrepancy of about 10°C is found in experiment.
