用Kramers-Kronig关系求出反射镜的相位色散
Application of Kramers-Kronig relations for calculating phase dispersion of reflective mirrors
【摘要】 光学元件相位色散在超短光脉冲的产生和传播中起着重要的作用,本文提出运用Kramers-Kronig关系,从反射谱直接求出反射镜的相位色散.文中对此法作了分析并以多层介质膜和铝膜反射镜为例子进行了讨论.
【Abstract】 The phase dispersion of optical elements plays an important role in the generation and transmission of ultrashort pulses. In this paper we put forward a method for directly calculating the phase dispersion of reflective mirrors from reflective spectra by using Kramers-Kronig relations. Taking multi-layer dielectric coating and Al coating as examples, the method is analysed and discussed.
