Spectral Shaped Aperture Component

A dichroic (or multichroic) beam splitter operating in the high energy laser HEL environment is called a shared aperture component and is becoming an increasingly desirable component in the design of HEL systems. At present, there are four basic types: Buried Short Period (BSP) grating, Buried Long Period (BLP) grating, Dichroic Beam Splitter (DBS) and Component Interlaced (CI) grating. The BLP and CI gratings are new types of grating that have recently been proposed and are currently under development. The four basic shared aperture components and their characteristics, their design and fabrication issues, and present technology status are described in this paper.© (1981) COPYRIGHT SPIE--The International Society for Optical Engineering.
