Abstract

Coupled cycloidal diffractive waveplates (CDWP) can be used for double diffraction or collinearly propagation of laser radiation of the corresponding wavelength. Adding a doubly refracting and dichroic film between them enables one to obtain the finite transmission even in the absence of double refraction. Both in the cases of two parallel and antiparallel vector gratings, we have an achromatic transmission in the case of strong absorption (as well as in the case of the absence of anisotropic refraction).

一对摆线衍射波片的线偏振光传输

摘要

耦合摆线衍射波片 (CDWP) 可用于相应波长的激光辐射的双衍射或共线传播。在它们之间添加双折射和二向色膜，即使在没有双折射的情况下也能获得有限的透射率。在两个平行和反平行矢量光栅的情况下，我们在强吸收的情况下（以及在没有各向异性折射的情况下）都有消色差透射。
