Abstract
Stimulated thermal Brillouin scattering-a phenomenon which exists in absorbing media-has been experimentally investigated. The gain of a light amplifier was measured as a function of frequency, absorption coefficient, and time during the laser pulse. The striking difference between absorbing and nonabsorbing liquids was found to be in excellent agreement with theoretical predictions.Keywords
