stimulated raman scattering microscopy for rapid

  • OSA

    Stimulated Raman spectroscopy has become a powerful tool to study the spatiodynamics of molecular bonds with high sensitivity resolution and speed However the sensitivity and speed of state-of-the-art stimulated Raman scattering spectroscopy are currently limited by the shot-noise of the light beam probing the Raman process Here we demonstrate in a proof-of-principle experiment an
