反射光栅的色散特性研究

Research of dispersion properties of reflective grating

本文分析了反射光栅的各种色散特性,提出光栅时间色散的概念,推导了光栅对光脉冲一级衍射的数学表达式。

This paper analysis the dispersion features of various gratings and presents the concept of the RGTD(reflective grating time dispersion). On this basis, the first order diffraction formula of the optical pulse is demonstrated.
