This report discusses the design and installation of a static wavefront correction optic on the HELEN laser at AWE. The element is designed to compensate for static phase errors and prompt thermally induced aberrations on the backlighter beam of the laser. Partial compensation of cooling effects is also included in the design. A phase element has been fabricated using a recently developed novel wet etch figuring tool at LLNL. Performance evaluation through comparison of the focal spot pre- and post-installation is provided. The element has been tested on the laser to produce a 2x reduction in focal spot size. |
