摘　　要：详细介绍了基于受激布里渊散射(SBS)光限幅原理的时域脉冲波形的研究进展.分析了一次SBS光限幅、种子场诱导的SBS光限幅和2次SBS光限幅的时域脉冲波形.1次SBS光限幅时域脉冲波形前沿出尖峰后边是平台;种子场诱导的SBS光限幅时域平顶脉冲波形类似于平顶;2次SBS光限幅时域脉冲波形是平顶.SBS光限幅时域平顶脉冲波形的获得对SBS的应用研究开辟了新的领域.The research development of time-domain pulse waveform by the stimulated Brillouin scattering （SBS） optical limiting is introduced. The pulse waveforms are analyzed in the situations of single SBS optical limiting, seed-induced SBS optical limiting and double SBS optical limiting. There is apeak in the front and a platform in the back of the waveform by single optical-limiting; the top is similar to a platform by seed-induced SBS optical limiting; the top is almost a platform by double optical limiting. The acquirement of flat-topped waveform in time domain provides the new field for the applications of SBS.
