远场的薄色散介质对超短脉冲的影响
Influence of Thin Dispersive Medium on Ultrashort Pulsed Gaussian Beams in the Far Field
摘要
时空耦合效应导致超短脉冲在远场频谱分布的复杂性。这种复杂性使放置于远场的薄色散介质对光脉冲同时产生时间展宽和波前弯曲等变化。同时给出了解析结果和数值计算实例。
Abstract
The far field spectral distributions of ultrashort pulsed Gaussian beams are greatly influenced by space- time coupling. Because of the complex spectral distributions, thin dispersive medium will not only broaden the pulse temporal widths but also change the curves of the pulse fronts. The analytical results are supported by numerical simulations of certain pulsed beams and dispersive medium.
