Surface-enhanced femtosecond stimulated Raman scattering (SE-FSRS) is one form of surface-enhanced coherent Raman scattering (SECRS) techniques that are ideally suited for observing the molecule-plasmon interactions involved in chemical change driven or enhanced by plasmonic nanomaterials. As plasmonic nanomaterials have seen diverse uses from optical nanoantennas to chemical nanoreactors, further developing techniques that can both initiate and track these chemical changes, like SE-FSRS is highly important. To this end, we have developed a variety of tools to further the use of SE-FSRS as an analytical technique. In this talk I will discuss our recent work in new SE-FSRS experiments that include building a 1 MHz SE-FSRS spectrometer, understanding the interplay between enhancement in extinction, and for the first time, stimulated Raman loss (SRL) in SE-FSRS. Further developing SE-FSRS experimentally and theoretically will allow for an improved analytical technique that can probe coupled molecule-plasmon interactions, potentially leading to a SECRS spectroscopy that can be used for initiating and tracking plasmonic chemistry.
