pulse envelope

基本解释

The pulse envelope we obtained is a hyperbolic secant function of time.
所得脉冲包络为时间的双曲正割函数。
With the development of few-cycle pulses (FCP), the phase shift of the optical carrier with respect to the pulse envelope becomes non-negligible.
在本文中，我们从几周期脉冲的载波相位出发，对超短光脉冲的一些基本问题进行了探讨。
And a theoretical model is established to expound the variation of pulse duration and the modulation on the pulse envelope similar to the diffraction characteristics in spatial domain.
通过与光束的空间传输特性类比解析了光栏宽度变化引起的脉宽变化以及脉冲轮廓出现时间衍射调制现象；
