The time evolution of the intensity of stimulated Brillouin scattering has been studied experimentally during transverse laser pumping of carbon disulfide filling a glass capillary. The scattered light was detected from the ends of the capillary. Large-scale temporal oscillations of the scattering intensity are observed, with time intervals on the order of and greater than the time taken by the light to traverse the length of the capillary twice. A small-scale temporal modulation is also observed. The modulation periods are equal to the period of the hypersonic wave in the stimulated Brillouin scattering and its subharmonics. © 1994 American Institute of Physics.
