Abstract
Time resolved coherent anti-Stokes Raman spectroscopy has proven to be a powerful tool for studying the dephasing of molecular vibrations /1/. Excitation and delayed probing is usually performed with single high power picosecond pulses from Nd glass lasers. Up to now widespread application of this technique to study the decay of coherent optical phonons in solids was excluded by the lack of suitable sources for simultaneous generation of picosecond pulses with a material dependent difference frequency. In this paper a CARS-spectrometer with two synchronously mode-locked cw dye lasers parallely pumped by a mode-locked Ar+ laser is described. It has been applied to explore the decay of coherent lattice vibrations in GaP and the dephasing of molecular vibrations in Toluene.
