Abstract

Reducing or eliminating reflectance of electromagnetic radiation from surfaces has important technical and commercial applications. Graded-index surfaces are of interest because they have low reflectivity over much broader spectral regions and angles of incidence than conventional thin film coatings. This paper reviews methods to calculate the reflectivity and to estimate the refractive-index profile of graded-index surfaces. Charactertistic properties and techniques to produce graded-index surfaces are reviewed. The results of recent measurements of laser-induced damage to graded-index surfaces are summarized.
