This paper reports the fabrication of the periodically poled 6mol% MgO doped LiNbO3 (PPMgLN) and the demonstration of the PPMgLN-based optical parametric oscillators (OPOs). The PPMgLN wafer was fabricated by high voltage pulse trigged domain reversal technique with periods ranging from 27.8—31.6μm by a step of 0.2μm. The OPO has a wide spectral tuning range from 1.42—1.73μm (for the signal) and 2.76—4.27μm (for the idler) while the wavelength of the pump is 1.064μm. In the experiment, the output power of 4.8W (the sum of the signal and the idler) was achieved when the input pumping power was 10.6W and the slope efficiency was computed to be 47%.
