摘要
报道基于6mol%镁掺杂的周期性畴反转掺镁铌酸锂(PPMgLN)的宽调谐光参量振荡器(OPO).PPMgLN采用外加电场法制作,周期为27.8—31.6μm,周期间隔为0.2μm.光参量振荡器的抽运源采用输出为1.064μm的声光调Q的Nd3+:YVO4激光器,其调谐范围为1.42—1.73μm(信号光)和2.76—4.27μm(闲散光),斜率效率达到47%.在输入功率为10.6W时,输出功率达到4.8W(信号光和闲散光之和).
This paper reports the fabrication of the periodically poled 6 mol% 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 27.8-31.6 μm by a step of 0.2 μm. The OPO has a wide spectral tuning range from 1.42-1.73 μm （for the signal） and 2.76-4.27 μm （for the idler） while the wavelength of the pump is 1.064 μm. In the experiment, the output power of 4.8 W （the sum of the signal and the idler） was achieved when the input pumping power was 10.6 W and the slope efficiency was computed to be 47%.
