Abstract

In order to measure the Brillouin linewidth of SBS medium, a method using mixture media in two-cell stimulated Brillouin scattering (SBS) system is proposed, which uses the medium to be measured as amplifier medium and the mixture media as generator medium. The profile of gain coefficient versus the difference of Brillouin frequency shift is fitted with Lorentzian curve. The width at half-maximum of this curve is the Brillouin linewidth. In the experiment, using Nd:YAG Q-switched laser system and CCl₄/C₆H₆ mixture, we measured the Brillouin linewidth of SBS media tetrachloroethylene (C₂Cl₄), hexachlorobutadiene (C₄Cl₆), acetone (C₃H₆O) and n-hexane (C₆H₁₄). The results show that the measured values are close to those calculated or published by other authors.
