Paper Abstract

At Rocketdyne, we have written an interactive 2-D diffraction beam train computer code which is used to predict the corrective capabilities of deformable mirror adaptive optics on lower order aberrations introduced by imperfections in optical components and by slight system misalignment. Operationally, this code utilizes the Fast Fourier Transform algorithm for beam propagation, specifies optical component aberrations in terms of Zernike polynomial series as synthesized from their interferograms or in terms of a multivariate distribution random phase generator, and corrects the accumulated aberration with a continuous deformable mirror whose actuators are modeled by bicubic splines. System performance is described in terms of the Strehl ratio, irradiance, and the encircled energy distribution on the fusion target. This code is being used to conduct a conceptual design and trade-off study on the merits of using deformable mirror adaptive optics for the Helios fusion laser system at the Los Alamos Scientific Laboratory, at infrared and at ultraviolet wavelengths.
