Abstract :
Based on a photonic crystal fibre (PCF) pumped by an ytterbium-doped fibre laser, a high-efficiency all-fibre optical parametric oscillator (OPO) is demonstrated. The high conversion efficiency is guaranteed by the relatively low intra-cavity loss of the all-fibre configuration. In the experiment, an internal conversion efficiency of up to 36% is achieved, which is believed to be the largest value for PCF-based OPOs.
