Super-resolution Raman Microscopy by selective suppression of stimulated Raman scattering (Conference Presentation)
Author(s): Sang-Hee Shim

Paper Abstract

For developing diffraction-unlimited Raman microscopy, a three-beam femtosecond stimulated Raman scattering (SRS) is deviced for simultaneously inducing two different SRS processes associated with Raman-active modes in the same molecule. Two SR gains involving a common pump pulse and two separate Stokes beams are coupled and compete: one SRS is selectively suppressed as the other Stokes beam intensities increases. Our theoretical description and experimental evidence support that the selective suppression behavior is due to the limited number of pump photos used for both of the two SRS processes. We anticipate a potential of this new switching-off concept in super-resolution label-free microscopy.
