摘要：

A high power, high-conversion-efficiency, and tunable continuous-wave external cavity pump singly resonant optical parametric oscillator (OPO) was proposed in this article. This OPO was based on multi-grating MgO-doped stoichiometric periodically poled LiTaO3 (MgO:sPPLT) and pumped with 532 nm continuous wave fiber laser. The MgO:sPPLT-OPO could provide near-infrared radiation across 821-879 nm in the signal and 1352-1515 nm in the idler within four grating periods of 8.3-8.6 mu m. When the pump power was 5.4 W, the maximum pump-to-signal conversion efficiency could reach 57.5% at 821 nm. The output power extended to 5.9 W in each period when the pump power reaches 13.6 W.
