Abstract

We describe development of passive phase correction elements to compensate for static phase errors and prompt thermally induced aberrations in the HELEN laser at AWE. Partial compensation of cooling effects is also included in the design. Phase elements have been fabricated through two processes, an indirect write lithographic process using amplitude masks generated from measured laser wavefronts and a direct write method using a novel wet etch figuring tool.
