Effect of Length of Reshaping Amplifier on Pulse Shape Controled by two Brillouin Amplifiers
修整放大池对双布里渊放大池控制脉冲波形的影响

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.
