Single-shot two dimensional time resolved coherent anti Stokes Raman Scattering.
Single-shot time resolved Coherent Anti-Stokes Raman Scattering (CARS) is presented as a viable method for fast measurements of molecular spectra. The method is based on the short spatial extension of femtosecond pulses and maps time delays between pulses onto the region of intersection between broad beams. The image of the emitted CARS signal contains full temporal information on the field-free molecular dynamics, from which spectral information is extracted. The method is demonstrated on liquid samples of CHBr(3) and CHCl(3) and the Raman spectrum of the lowlying vibrational states of these molecules is measured.
