摘　　要：利用受激布里渊散射放大时抽运光与种子光可以有一时间延迟的特性,设计了一个同轴传播正交偏振双脉冲序列的偏振控制装置,使同轴传播的两个正交偏振脉冲光束在放大时具有相同的偏振态,从而实现了两束光的抽运放大.Using the characteristic that a time delay between the signal of stimulated Brillouin scattering （SBS） and the pump beam during amplification of SBS signal is allowed, a controller is devised to control the polarizations of two pulses propagating collinearly with orthogonal polarizations. It makes the two beams have the same polarization when the SBS signal meets the pump beam. Therefore, amplification of the SBS signal is realized.
