Abstract
We have introduced the additional prepulse with main pulse to generate the stimulated Brillouin scattering (SBS) and investigated the effect of this technique. In general, temporal pulse shape deformation takes place when the pulse is reflected from the medium breeding SBS. This deformation of the SBS wave can cause optical breakdown in the optical components and consequently it leads to low reflectivity and low fidelity of the phase conjugated wave in the SBS medium. It has been shown that there is optimum prepulse time delay and minimum energy for preserving the SBS waveform. This method is so simple that it can be applied to other systems and utilized in many applications easily, such as high-power laser and optical isolator applications employing several SBS cells.
