摘　　要：利用受激布里渊散射(SBS)获取相位共轭光波是实现光学相位共轭最简单有效的方法,然而实际应用中总伴随着SBS脉冲压缩,导致时域脉冲波形发生改变。为了在应用受激布里渊散射相位共轭镜时获得更好的波形保真度,对受激布里渊散射过程中Stokes脉冲波形的控制进行了研究。通过提升受激布里渊散射过程中的瞬态增益,可以在泵浦脉冲时域上更早的产生Stokes信号,从而获取高波形保真度的相位共轭激光脉冲。Stimulated Brillouin scattering(SBS)is one of the most efficient methods to achieve optical phase conjugation.However,practical SBS phase conjugation applications is always accompanied pulse compression,resulting pulse waveform change.To obtain better waveform fidelity while applying the stimulated Brillouin scattering phase conjugate mirror,pulse control in stimulated Brillouin scattering process is investigated experimentally.By raising the energy density of the injected pump pulse,a higher transient gain is provided,and the stokes signal is generated earlier at time domain.With the control of pump intensity,the stokes pulse with high waveform fidelity is achieved.
