摘要	We present a miniaturized idler-resonant all-fiber-laser-pumped optical parametric oscillator (OPO) based on MgO:PPLN. The conversion-efficiency and beam-quality performances of the idler- and signal-resonant OPOs with flat-flat cavity are first compared. The idler-resonant OPO MIR beam quality is better than that of the signal-resonant one, but the idler conversion efficiency is lower. Next, we examine the influence of the outputcoupler curvature radius, pump-beam-waist radius, and cavity length on the MIR conversion efficiency and beam quality of the idler-resonant OPO. Post optimization of these factors, we report a maximum MIR power of 5.84 W at 3.76 mu m, conversion efficiency > 14.0%, and M-2 factors of 1.57 and 1.49 along the horizontal and vertical directions, respectively.
