Abstract
We report all-UV coherent anti-Stokes Raman scattering (CARS) in calcite with pump, Stokes, probe, and anti-Stokes light. UV CARS efficiency is higher than for comparable scattering in the visible, . Time-resolved UV CARS reveals lengthening of the dephasing time of internal vibrations from with increasing vibrational excitation, consistent with a phonon depletion model.
