LAYERTEC 啁啾镜对 (超快激光反射镜)-筱晓（上海）光子技术有限公司

(Chirped Mirror Pair)啁啾镜用于补偿超短激光脉冲与色散相关的传播时间差。如果 GDD 曲线中的振荡很强，则需要啁啾镜对（由两个啁啾镜组成）。对于高带宽的镜子尤其如此。

啁啾镜的 GDD 曲线并不代表直线曲线，而是显示振荡。其中，这些强度有多强取决于光谱带宽。对于小于同类布拉格镜带宽的 GDD 带宽，振荡相当小。另一方面，具有高带宽的镜子表现出强烈的 GDD 振荡。

负色散镜对的 GDD 光谱

可以通过使用相应的镜对来实现校正。它们由两个具有相反 GDD 曲线的不同涂层介电镜组成，激光束可以根据需要在两个镜之间来回反射（见图）。这些镜子针对小入射角进行了优化，从而可以实现大量反射。
