摘要

飞秒、宽带受激拉曼光谱是测量分子动力学的一种流行方法，具有优异的信噪比和光谱分辨率。我们提出了一种宽带受激拉曼光谱的新方法，该方法使用Kerr不稳定性放大来放大蓝宝石的超连续光谱，并创建一个高度可调谐的拉曼探针光谱，范围从530到1000 nm（-6000到2800 cm-1）。我们的方法，称为克尔不稳定性放大的宽带受激拉曼光谱（KAB-SRS），通过产生更宽、更可调的光谱，以显着降低OPA实现的成本，为光学参数放大器提供了一种替代方案。我们通过测量1-癸醇的受激拉曼损失谱来证明KAB-SRS的有效性。

Stimulated Raman Spectroscopy Using a Tunable Visible Broadband Probe Pulse Generated by Kerr Instability Amplification.

Femtosecond, broadband stimulated Raman spectroscopy is a popular approach to measuring molecular dynamics with excellent signal-to-noise and spectral resolution. We present a new method for broadband stimulated Raman spectroscopy that employs Kerr instability amplification to amplify the supercontinuum spectrum from sapphire and create a highly tunable Raman probe spectrum spanning from 530 to 1000 nm (-6000 to 2800 cm^-1). Our method, called Kerr instability amplification for broadband-stimulated Raman spectroscopy (KAB-SRS) provides an alternative to optical parametric amplifiers by producing a broader and more tunable spectrum at a significantly reduced cost to OPA implementations. We demonstrate the effectiveness of KAB-SRS by measuring the stimulated Raman loss spectrum of 1-decanol.
