摘　　要：以高斯、双曲正割、洛伦兹3种脉冲为例,研究了载波相位与超短脉冲携带的能量之间的关系,给出了3种脉冲携带的能量与载波相位的解析表达式.研究结果表明,当脉冲包络的宽度短于1个光学振荡周期时,载波相位对超短脉冲携带的能量开始有较显著的影响.The relations between the ultrashort pulse energy and the carrier phase are studied by using three kinds of ultrashort pulses, namely Gauss,hyperbolic secant and Lorentz pulses. The analytical expressions between the ultrashort pulse energy and the carrier phase are deduced. It is found that the carrier phase affects the pulse energy seriously when the pulse width is shorter than one optical oscillation period.
