Wide-field coherent anti-Stokes Raman scattering microscopy based on picosecond supercontinuum source

We present a wide-field coherent anti-Stokes Raman scattering microscopy setup based on picosecond-laser-pumped supercontinuum and use it to demonstrate video-rate imaging with chemical specificity. The broadband excitation allows simultaneous imaging of a wide range of Raman modes, and chemically selective imaging is achieved by applying filters corresponding to the anti-Stokes Raman bands.
