摘要：

We described a widely tunable intracavity continuous-wave singly resonant optical parametric oscillator (SRO) through a minimal laser diode end-pumped Nd:YVO4 laser. Laser source from 1.9 mu m to 2.4 mu m is obtained by temperature tuning of the 32.2 mu m period periodically poled MgO:LiNbO3(PPMgLN) crystal. The maximum power, 0.84W signal wave at 1.966 mu m and 0.56W idler wave at 2.319 mu m, are simultaneously obtained at 5.5 W of input diode power. The corresponding conversion efficiency are 15.2% and 10.2% respectively, so the whole efficiency is more than 25%. This allows the development of practical infrared cw SRO's using compact, widely available, low-cost laser pump sources.
