Femtosecond stimulated Raman microscopy (FSRM) is a nonlinear technique for rapid broadband Raman imaging. It utilizes a few femtosecond probe pulse and a narrow bandwidth pump pulse. Using a fast (20 kHz) multi-channel detector, stimulated Raman spectra can be recorded with an acquisition time as short as 0.1 ms. In this Letter, spectra of neat benzonitrile at different acquisition speeds are presented to benchmark the FSRM setup. Furthermore, chemical maps of a multi-phase polymer blend are recorded using the fastest acquisition rate possible with the current instrument.
飞秒受激拉曼显微镜（FSRM）是一种用于快速宽带拉曼成像的非线性技术。它利用几个飞秒探测脉冲和一个窄带宽泵浦脉冲。使用快速（20 kHz）多通道探测器，受激拉曼光谱可以在短至0.1 ms的采集时间内记录下来。在本信函中，展示了不同采集速度下纯苯甲腈的光谱，以对FSRM装置进行基准测试。此外，使用当前仪器可能的最快采集速率记录了一种多相聚合物共混物的化学图谱。
