摘　　要：以Gauss、HyperbolicSecant、Lorentz三种脉冲为例,利用理论推导和数值模拟的方法研究了载波相位对超短脉冲时间重心的影响,并给出了三种脉冲的时间重心与载波相位的解析表达式和数值模拟的图形·研究结果表明:当脉冲包络的宽度短于一个光学振荡周期时,载波相位对超短脉冲的时间重心开始有较显著的影响·The relation between the center of time gravity of the ultrashort pulse and the carrier phase was studied by using three kinds of pulses,named Gauss, Hyperbolic Secant and Lorentz pulses. The analytical expressions of the relation between them was deduced. The results show that the carrier phase affects the center of time gravity of the ultrashort pulse seriously when the pulsed width is shorter than the optical oscillation duration.
