Abstract

Nonlinear holographic gratings are of interest in laser systems for sampling beams from the primary mirror of a large beam expander. The sampled beam is then used for wavefront control purposes. This paper discusses the optical design and geometrical properties of the grating and its construction optics. The design and performance of a 30-cm aperture bread-board covering a 4-inrad field of view with an 8X, f/1.5 beam expander are then discussed. The wavefront aberration differences between the sampled and laser beams are corrected to within a maximum error of 0.3 µm.
