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+1} π/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+1} π/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+3} π/4和{4n+1}π/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.
In the time domain, the influence of carrier phase on ultra-short sinusoidal Gaussian pulse is studied. The analytical expression and numerical simulation of the pulse energy and time center of gravity of the ultra-short sinusoidal Gaussian pulse are given. The results show that the parameters of carrier phase and sine function are The pulse energy of the ultra-short sinusoidal Gaussian pulse has a great influence on the time center of gravity. When the carrier phase is equal to nπ and {2n + 1} π / 2, the pulse energy of the ultra-short sinusoidal Gaussian pulse reaches the minimum and the maximum respectively. When the phase is equal to {2n + 1} π / 4, the carrier phase has no effect on the pulse energy of the ultra-short sinusoidal Gaussian pulse. When the carrier phase is equal to {4n + 3} π / 4 and {4n + 1} π / 4 The center of gravity of the short sinusoidal Gaussian pulse reaches the minimum and maximum values respectively. When the carrier phase equals nπ / 2, the time center of gravity of the ultra-short sinusoidal Gaussian pulse does not change.
