Temperature dependence of threshold and gain coefficient of stimulated Brillouin scattering in water
Abstract
Temperature dependence of threshold and gain coefficient of stimulated Brillouin scattering (SBS) was investigated. It was found that the threshold of SBS decreases with the increase of temperature. Based on the definition of the threshold, a new method was proposed for determining the gain coefficient of SBS of the material experimentally by measuring the threshold. It reveals that the threshold and the gain coefficient of SBS of a material are strongly related to temperature.
