Terahertz beats of vibrational modes studied by femtosecond coherent Raman spectroscopy

R. Leonhardt , W. Holzapfel , W. Zinth , W. Kaiser

A recently developed femtosecond coherent Raman technique allows the measurement of Fourier transform coherent Raman spectra with high-frequency differences. The simultaneous excitation of different vibrational modes with a broad-band tunable driving force leads to a strong beating of the coherent Raman probe scattering. The high time resolution of the experimental set-up allows one to measure beat frequencies of more than 10 THz with high precision.
