摘要:
Stimulated Brillouin scattering characteristics are formulated for the case of a multiple‐short‐pulse pump. Simplified stimulated Brillouin scattering equations in the small‐ and large‐gain limits are solved for the Stokes intensity giving the dependence on the pulse width and delay, and pulse number. Coherent and incoherent intensities were also calculated and a quadratic versus linear dependence, respectively, on the pulse number was found. It is shown that the gain is largely unaffected by the appearance of a pulsed pump; however, the intensity is roughly reduced by the ratio &tgr;p/&Dgr;, where &tgr;pis the pulse width and &Dgr; is the sum of the pulse width and separation.
