Abstract

The composition and time evolution of the Stokes pulse spectram have been studied. A cell with CCl₄ was pumped with the radiation from the TEM₀₀ YAG:Nd laser with the electrooptic shutter. Its spectrum consisted of several (1-6) longitudinal modes whose number chnaged stochastically from pulse to pulse. The SBS spectrum of the laser pulse compressed from 8ns to 1.2ns consisted predominantly of one frequency or, rarely, of two to three ones. The chronography of the Fabry-Perot interference pictures of the Stokes pulse showed simultaneous excitation of these frequencies.
