    Abstract

    A representative set of dielectric coatings prepared using novel deposition techniques have been evaluated. Single layer coatings of ZrO2 and Al2O3 were deposited on super polished fused silica substrates by conventional electron beam, electron beam in UHV, electron beam with ion beam assist, CW laser in UHV, and an advanced epitaxial technique. Characterization included total integrated scatter, spectrophotometry, x-ray diffractometry and pulsed laser damage testing at 532 nm. Our results indicate that considerable additional work will be required to optimize the optical performance of coatings produced by these novel deposition methods, let alone understand the relationship between deposition process, structure, optical characteristics and durability.
