Abstract

In order to understand the stimulated Brillouin scattering (SBS) process in water, it is necessary to analysis theoretically the factors which to determine the SBS gain coefficient and threshold. The coupled wave equation is used to investigate the effects of temperature, salinity and attenuation coefficient on SBS gain coefficient and threshold. The results indicate that the higher the temperature and salinity, the greater the SBS gain. And the threshold is negatively correlated with the temperature. The effects of attenuation coefficient on threshold of steady-state SBS is greater than transient SBS.
