Pushing the limits of nonlinear Raman microspectroscopy

摘要

Nonlinear Raman microspectroscopy is a promising advanced spectroscopic technique capable of providing chemically specific information completely noninvasively. Signal collected from a microscopic volume can be acquired at a rate significantly exceeding the one for conventional Raman scattering imaging. In this report we analyze the current limitations from the point of view of the signal-to-noise optimization and propose several solutions to outstanding technical problems.
