Characteristics of the output pulse shape of stimulated Brillouin scattering optical limiting process induced by the seed field is numerically simulated. Rules of limiting pulse shape controlled by the seed field are obtained as follows: When seed pulse duration is chosen to be five times as that of the pump pulse duration, and delay time is just the same as that of pump pulse duration, the best limited temporal profile can be obtained. At the same time, it is affected by the pump power: as the pump power increases, it falls endlessly before it becomes zero. Study indicates that controlling of SBS optical limiting pulse shape can be achieved by using a seed pulse.
