Abstract

We describe the theoretical treatment of the pump-enhanced singly resonant optical parametric oscillator (OPO) in which pump and signal simultaneously resonate in the cavity. The research shows that the photon conversion efficiency of pump-enhanced singly resonant OPO is related to the reflectivity of input coupler and the incident power ratio. Under specific incident power ratio, the maximum photon conversion efficiency can be obtained in the region where impedance matching is met. Considering the pump linear loss of 0.9% in the ring cavity, the maximum value of photon conversion efficiency is 99.6% that is higher than singly resonant OPO.
