| 摘 要： | 在时间域中研究了载波相位对超短正弦高斯脉冲的影响.给出了超短正弦高斯脉冲的脉冲能量和时间重心的解析表达式和数值模拟结果.结果表明载波相位和正弦函数的参数对超短正弦高斯脉冲的脉冲能量和时间重心有很大的影响.当载波相位等于nπ和2n+1π/2时,超短正弦高斯脉冲的脉冲能量分别达到最小和最大值;当载波相位等于2n+1π/4时,载波相位对超短正弦高斯脉冲的脉冲能量没有影响.当载波相位等于4n+3π/4和4n+1π/4时,超短正弦高斯脉冲的时间重心分别达到最小和最大值;当载波相位等于nπ/2时,超短正弦高斯脉冲的时间重心不发生变化.

| Abstract: | The influences of the carrier phase on the ultrashort sine-Gaussian pulse were studied in time domain.Expressions of the pulse energy and the center of time gravity were deduced,and some numerical results were given.It is found that the carrier phase and the parameter of sine function affect the pulse energy and the center of time gravity seriously when the pulse width is shorter than one optical oscillation period.The pulse energy of sine-Gaussian pulse reaches respectively the minimum and maximum when the... |
