To add I/ O interface filtering board between control group and power amplifier. 在控制组合和功放之间加装I/O口滤波板。
Numerical calculation proves that the differential group delay between two components after the first amplifier becomes much smaller in polarization-dependent lumped amplification scheme with nonlinear gain, which means that the periodical pulse splitting and mergence interactions are suppressed efficiently. 数值计算结果表明:采用具有非线性增益的偏振相关集总放大方案,经过第一个放大器后脉冲的差分群时延变小,这说明了周期性的脉冲分裂&融合碰撞行为得到了有效的抑制。
