ABL subscale deformable mirror risk reduction tests

摘要

An account of the recently completed, 1-1/2 year ABL risk reduction deformable mirror (DM) program will be given. In this effort, candidate sub-scale deformable mirrors (SSDM) supplied by tow vendors were tested for manufacture and performance quality. The down-selected mirror was then provided with a newly-developed, high performance, multiple wavelength, low stress, very low absorptance faceplate optical coating. The SSDM was then operated for cycle number and stroke, and under high laser flux, that exceeds the operational requirements of the ABL DMs. The successful results for these tests, carried out with the contributions of a multifaceted integrated product team, will be reported.
