报道了一种基于周期极化掺镁LiNbO_3(PPMgLN)的光纤型宽调谐连续中红外DFG/QPM激光器，该光源以掺YdFL光纤激光器(YDFL)为泵浦光源，以掺铒光纤放大器(EDFA)级联的EDFL激光器为信号源。实验结果表明，在泵浦方向和信号偏振方向平行于晶体主光轴的情况下，可以优化转换效率。抽运光斑和信号光斑及其纵向演化行为决定了RCE和晶体纵向位置公差，对于中红外激光光源，这两个公差分别为0.717(MW)-2和44 mm。中红外DFG/QPM激光光源的怠速输出可在3.1RCE3.1~3.6RCEm范围内连续调谐，且RCE值基本相同。
In this paper we report a fiber-type widely tunable CW mid-IR DFG/QPM laser source based on periodically poled MgO-doped LiNbO3 (PPMgLN), which uses a ytterbium-dope fiber laser (YDFL) as the pump source and a tunable erbium-dope fiber laser (EDFL) cascaded with an erbium-doped fiber amplifier (EDFA) as the signal source. Our experimental results show that, with the PCs to adjust the pump and signal polarization orientations being parallel to the crystal principle optical axis the conversion efficiency may be optimized. The pump and signal beam spots and their longitudinal evolution behaviors determine the RCE and the crystal longitudinal position tolerance, which are measured to be 0.717 (mW)-2 and 44 mm for the mid-IR laser source, respectively. The idler output of the mid-IR DFG/QPM laser source may be continuously tuned from 3.1 to 3.6 μm with almost the same RCE.
