Abstract

Hyperspectral coherent Raman scattering microscopy provides a significant improvement in acquisition time compared to spontaneous Raman scattering yet still suffers from the time required to sweep through individual wavenumbers. To address this, we present the use of a pulse shaper with a 2D spatial light modulator for phase- and amplitude-based shaping of the Stokes beam to create programmable spectrally tailored excitation envelopes. This enables collection of useful spectral information in a more rapid and efficient manner.

摘要

与自发拉曼散射相比,高光谱相干拉曼散射显微镜在采集时间上有显著改善,但仍受逐个扫描波数所需时间的困扰。为解决这一问题,我们提出使用带有二维空间光调制器的脉冲整形器,对斯托克斯光束进行基于相位和幅度的整形,以创建可编程的光谱定制激发包络。这使得能够以更快、更高效的方式收集有用的光谱信息。
