Large-Aperture Grating Tiling by Interferometry for Petawatt Chirped-Pulse--Amplification Systems
- Laboratory for Laser Energetics, University of Rochester
A tiled-grating assembly with three large-scale gratings is developed with real-time interferometric tiling control for the OMEGA EP Laser Facility. An automatic tiling method is achieved and used to tile a three-tile grating assembly with the overall wavefront reconstructed. Tiling parameters sensitivity and focal-spot degradation from all combined tiling errors are analyzed for a pulse compressor composed of four such assemblies.
