Abstract
The phase of molecular motion is modulated by the optical Stark effect due to high-intensity laser beams. This is shown to lead to modulation in coherent Raman spectra. The spectral modulation is more pronounced in stimulated Raman spectroscopy than in four-wave-mixing Raman spectroscopy. Increased damping reduces the phase modulation leading to the commonly known spectra.Keywords
