在宽带红外光源的和频产生框架中，我们的目标是在保持高转换效率的同时，通过使用泵浦频率梳来扩大转换带宽。在同一非线性介质中同时产生了非线性效应。在本文中，我们研究了光谱滤波效应的时间相干行为与马赫-曾德尔干涉仪使用两个泵浦线。我们表明，准相位匹配和光谱采样的联合效应导致原始的相干行为。
In the frame of sum frequency generation of a broadband infrared source, we aim to enlarge the converted bandwidth by using a pump frequency comb while keeping a high conversion efficiency. The nonlinear effects are simultaneously induced in the same nonlinear medium. In this paper, we investigate the spectral filtering effect on the temporal coherence behavior with a Mach-Zehnder interferometer using two pump lines. We show that joined effects of quasi-phase matching and spectral sampling lead to an original coherence behavior.
