Resolution of spectral focusing in coherent Raman imaging
Abstract:
In this manuscript, we present a detailed investigation of the impact of dispersion on the spectral resolution achievable by the application of spectral focusing in coherent Raman imaging. Our results reveal the detrimental effect of third order dispersion that limits the resolution for group delay dispersion of 100 000 fs2 and more. Experimental examples for the exact determination of the described effects are given as well as a condensed presentation of the known equations. We introduce useful approximations to the latter, which serve to facilitate the straightforward integration of spectral focusing into any multimodal microscope.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
