Amplification of stimulated Brillouin scattering by collinear laser pulse series with two orthogonal polarizations
同轴正交偏振双脉冲序列受激布里渊散射抽运放大的实现方法

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.
