Fabrication of blazed holographic optical elements on oxygen free copper by ultrahigh precision cutting

A holographic optical element (HOE) is a kind of diffractive optical element. An HOE can substitute an optical system with multiple optical components like lenses, mirrors, beam-splitters, prisms and so on. So it is expected to reduce the number of its optical parts, improve a performance of various optical systems, such as optical storage systems[1] like CD or DVD systems, optical instrumentations, fiber optics and etc., and make an optical system simple, small and light weighted.
