title: Phase measurement of coherent Raman vibrational spectroscopy with chirped spectral holography.
abstract: We introduce a nonscanning, time-domain sensitive phase measurement of Raman-active vibrations. Coherent vibrations are set up by impulsive stimulated Raman scattering and probed by spectral interferometry using a time-delayed pair of probe and reference pulses. The probe-reference pair is chirped, and the instantaneous frequency sweep maps spectral phase encoded in the pulses to the time-domain vibrational motion, allowing measurements to be made without a time-consuming pump-probe delay scan.
