| 摘 要： | 在传统独立双池结构的受激布里渊相位共轭镜系统中,引入修整放大池,采用主放大池与修整放大池相结合的双布里渊放大池放大控制脉冲波形.主放大池控制脉冲的整体波形,而修整放大池对脉冲波形,特别是脉冲前沿进行微调.修整放大池池长对双布里渊放大池放大控制脉冲波形的影响进行了理论研究和实验验证,得到了不同情况下脉冲波形随双池间距的变化规律.研究表明修整放大池池长决定放大光前沿的放大效率,是控制脉冲波形的重要参量.

| Abstract: | A reshaping amplifier is suggested in the system of stimulated Brillouin scattering phase conjugate mirror.This novel scheme of two Brillouin amplifiers can finely control output pulse shapes,in which the main amplifier coarsely controls the pulse shape and the reshaping amplifier fine-tunes the pulse shape,especially the leading edge of the pulse.Effects of the length of the reshaping amplifier on the pulse shape are theoretically and experimentally researched.Rules of pulse shape versus distance between the two amplifiers are achieved.Results show that the length of the reshaping amplifier decides the amplification efficiency and is an important parameter to control pulse shapes. |
