Abstract

We present in-line interferometric femtosecond stimulated Raman scattering (II-FSRS), a new method to measure the spectral Raman intensity and phase over a broad spectral range, potentially in a single shot. An analytic model is developed, that excellently reproduces the measured spectra. Additionally, the performance of II-FSRS is directly compared in experiments to two established techniques, namely femtosecond stimulated Raman scattering and femtosecond Raman induced Kerr-effect spectroscopy.

摘要

我们提出了一种新的方法——在线干涉飞秒受激拉曼散射（II-FSRS），可在单次测量中实现宽光谱范围内的光谱拉曼强度和相位的测量。我们建立了一个分析模型，可极好地重现所测量的光谱。此外，我们还在实验中直接比较了 II-FSRS 与两种已建立的技术（飞秒受激拉曼散射和飞秒拉曼诱导克尔效应光谱学）的性能。
