摘　　要：研究了带有线性啁啾的几周期高斯脉冲的主要时域特性 ,分析了载波相位对啁啾脉冲的影响。结果表明啁啾在很大程度上增大了载波相位发挥作用所对应的脉宽范围 ,并且相位对啁啾脉冲的作用比对无啁啾的情况更加显著。Some primary characteristics of linearly chirped few-cycle pulse with Gaussian profile have been studied in the time domain.Influences of the carrier phase on the chirped pulse have been analyzed.Results show that the chirp can substantially increase the extent of the envelope width where the carrier phase takes effect,and carrier phase plays a more important role in the condition of a chirped pulse than that of an unchirped one.
