Paper Abstract

A deposition system for laser flash evaporation was assembled and used to deposit onto polycarbonate SiOxNy rugate filters with optical densities as high as 2.5 and band-widths as low as 6.8% of the rejection wavelength. When coupled with feedback loop closure, installation of a real-time index and thickness monitor should provide the necessary control to produce higher quality rugate filters with multiple rejection lines and optical densities greater than 4.
