Investigation of the influence of temperature on threshold value and pulse duration of stimulated Brillouin scattering in liquid water

摘要

The threshold value and pulse duration of stimulated Brillouin scattering (SBS) have been measured over the temperature range 10-45C in liquid water. Also, a theoretical analysis based on the temperature dependence of SBS has been carried out. The results show that the threshold value of SBS decreases with an increase of temperature, whereas the measured pulse duration increases with an increase of temperature.
