Paper Abstract

An inherently fringe stable interferometer, with uniform recording-plane exposure, produces transmission gratings with uniformly high efficiency. The surface-relief structures recorded in positive photoresist are ideal for their transfer into specialized candidate materials. These structures have many applications in high-power lasers including beam smoothing, pulse compression, and low-reflection surfaces. Also, accurate modeling of surface-relief grating efficiencies, using the actual groove profile, allows optimization of grating parameters.
