We report two cw, singly resonant optical parametric oscillator (OPO) configurations based on periodically poled lithium niobate that result in significantly higher efficiency and output power than in previous studies. Using four-mirror OPO cavities and pumping with a 1.064-μm Nd:YAG laser, we observe 93% pump depletion and obtain ∼86% of the converted pump photons as useful idler output. The single-beam, in-the-bucket idler output power of 3.55 W at 3.25 μm corresponds to ∼80% of quantum-limited performance. We measure and compare the amplitude noise and spectral bandwidth of the two configurations. We also demonstrate >1 W of tunable cw output over the 3.3–3.9-μm spectral range.

  7. We define the idler quantum slope efficiency as the slope of the idler-versus-pump-power curve multiplied by the ratio of the idler and the pump wavelengths.
  8. Percentage quantum-limited performance, (Piλi)/ (Pp/λp), where Pi is the measured idler power, Pp is the incident pump power, and λp and λi are the pump and the idler wavelengths. At 100% quantum-limited performance, Pi would equal 4.4 W for Pi = 13.5 W, λp = 1.064 μm, λi = 3.25 μm.
