Paper Abstract

The authors have outfitted one beamline of Nova with random phase plates (RPPs) to spatially smooth the beam. The fabrication and characterization of large aperture (80-cm diameter) RPPs for use at 526.5 nm along with the performance of these optics on Nova are discussed. The present RPPs were fabricated by a conventional, although large scale vacuum deposition process. Fabrication of RPPs using a unique sol-gel coating process, which has been demonstrated at 15-cm diameter and can be scaled to the 80-cm diameter required for Nova, is also discussed.
