We report the first correlation measurement between the twin beams generated by optical parametric process above threshold. This high-visibility correlation can be observed at significant power levels with up to a conversion efficiency of 19.7%.
We demonstrate a high efficiency mid-infrared laser source based on optical parametric oscillator (OPO) assisted by an intracavity optical parametric amplification (OPA). The OPA-assisted-OPO scheme was realized in one piece of commensurable dual-periodic superlattice in which the signal light generated from the OPO process serves as the pump light for the OPA process. A maximum output power of 508...
We experimentally demonstrate cavity phase matching for the first time using a sheet optical parametric oscillator. It presents unique features such as high power capability, high slope efficiency, single-longitudinal-mode oscillation and narrow linewidth.
