Abstract

Abstract

Because of the reflection on the surface of the gratings, the diffractive efficiency of the components can't meet the requirement of the ICF system. To resolve the problem this paper introduces a kind of scheme adopted coating to reduce the reflection of the gratings' surface. The coating anti-reflection technology of the CSG is discussed in detail. Using the scalar theory the design parameters have been decided and the structure parameters of the gratings have been optimized. The optimized value of the trough depth of the CSG is 2.84μm, and the optimized value of the film depth is 71.2nm. The numerical results show that the reflection of the gratings' surface has been eliminated drastically. The validity of the anti-reflection technology is distinctly in the application of the high pow
- ：color separate grating (csg),
- diffractive efficiency,
- solgel film,
- coating anti-reflection technology.
