In this paper, the influences of medium temperature on threshold and gain coefficient of stimulated Brillouin scattering (SBS) in water are investigated theoretically and experimentally. Based on the theoretical analysis, a new method is proposed to determine the gain coefficient of SBS of the material by measuring the threshold. The experimental results indicate that the gain coefficient of SBS increases exponentially with the increase of medium temperature.
