我们展示了一种新的方法，四波混频光谱涉及在时域和频域，其中光谱选择性是通过相位匹配滤波实现的同时测量，并在一个单一的超短脉冲内获得的时间分辨率。我们分析了四波混频信号，并表明我们的方法是能够区分不同的振动相干调制散射信号的光谱路径。
We demonstrate a new approach to Four Wave Mixing spectroscopy involving simultaneous measurements at time and frequency domains, where spectral selectivity is achieved by phase matching filtering, and the time resolution is obtained within a single ultra-short pulse. We analyze the Four Wave Mixing signal, and show that our method is capable for discrimination between different spectroscopic pathways of vibrational coherences modulating the scattered signal.
