Phase-Modulation-Broadened Line Shapes from Micrometer-Size CS2 Droplets

摘要

Asymmetrically broadened line shapes observed in the stimulated Raman and elastically scattered spectra from a CS2 droplet are manifestations of phase modulation by means of the intensity-dependent index of refraction. Unique features of the droplet morphology in enhancing the internal fields at the input and Strokes wavelengths and in prolonging the decay times of the waves within the droplet, which acts as an optical cavity, are discussed.
