Abstract
The initial set of Distributed Phase Plate (DPP) optics for the Laboratory for Laser Energetics OMEGA Laser system were fabricated using an epoxy replication technique.1 A requirement for the final production of these epoxy DPP’s was the development of a sol-gel anti- reflection coating compatible with the UV epoxy material. Although ethanol based sol-gel coatings have been successfully applied to a variety of OMEGA components ranging from BK-7 and fused silica optics to KDP frequency conversion crystals, attempts to apply these coatings to epoxy DPP’s resulted in swelling and distortion of the replicated epoxy surface.2 To achieve a good anti-reflection coating on an epoxy replicated surface, the development of an aqueous based sol-gel (ASG) material was deemed essential.
