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). 关键词: 周期性畴极化掺镁铌酸锂 宽调谐光参量振荡器

关 键 词:周期性畴极化掺镁铌酸锂  宽调谐光参量振荡器

Abstract: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%.
Keywords:PPMgLN  widely tunable OPO
