The spatial and temporal sound wave distribution in stimulated Brillouin scattering (SBS) cells was calculated for focussed laser beams. The pump power was varied up to the saturation values. The spontaneous scattering was determined from comparison with experimental results. Using this model the influence of the pulse length, the focal length, the cell length and other parameters on the distribution of the sound wave and the SBS-reflectivity can be discussed.

AbstractIn order to improve the optical limiting performance based on stimulated Brillouin scattering (SBS), a combination of SBS and carbon nanotube/HT-270 suspension for optical limiting is proposed in this paper. The dependence of output energy of optical limiting based on this hybrid approach on the pump energy is numerically simulated, and validated in Continuum's Nd: YAG seed-injected laser. The results indicate that the output energy based on this hybrid approach shows much better performance compared with that based on single SBS. In this approach, the SBS threshold can be controlled by adjusting the gain coefficient of medium and focal length of the lens, and the threshold of suspension can be controlled by altering the concentration and focal length of the lens, therefore, this hybrid approach to realize optical limiting has great potential in practical application.
