Abstract

Broad angle antireflection coatings (BAAR) have been designed, fabricated and their damage thresholds determined at 1064 nm. Two layer AR coatings as well as four layer BAAR systems were designed using a refining program. The performance of both the coating systems was compared. Reflectance at normal and different oblique incidence angles, absorption and damage threshold are reported..
