The connection between stimulated Raman scattering and self-focusing was investigated both theoretically and experimentally. Special attention was given to 1 an explanation of the simultaneous occurrence of several order Stokes and anti-Stokes radiation and 2 an anomalous time behavior, which was found to be present, in the higher order Stokes and 1st anti-Stokes radiation, especially in carbon disulfide. The first phenomenon is explained by introducing a distribution of filament lengths, and good agreement is obtained between theory and experiment. It is suggested that the time anomaly is caused by dielectric breakdown, and numerical calculations are carried out showing qualitative agreement with the observed data. Author
