Abstract :
Using mathematical modeling and numerical simulations, we examine the image formation in CARS, FM-CARS, AM-SRS and FM-SRS nonlinear Raman-based modalities. We find that in the presence of a nonresonant spatially-nonuniform background medium, only the FM-SRS modality can be considered to be both background and distortion free.
