Paper Abstract

Interest in vacuum ultraviolet optical coatings has increased in recent years, due to applications in space research, laser fusion, photochemistry, and analytical chemistry. A number of new high-efficiency coatings have been developed to satisfy the requirements of these applications. Material limitations, more severe than those in the visible and IR, have limited broadband reflectors to 80-85% average reflectivity in the 1200-2000 A region. A new technology of multilayer dielectric coatings for the vacuum UV, beginning in 1973, has led to laser reflectors with reflectances as high as 95% at wavelengths as short as 1460 A. Dichroic coatings with maximum reflectance in one spectral region and high transmission in another were developed for applications in UV pumping of longer-wavelength lasers, Raman shifting of UV laser lines, and generation of UV harmonics. Very narrow-band interference filters, multilayer dichroic reflective filters, and neutral density filters have been fabricated for rocket spectroscopy applications, as have high-efficiency UV AR coatings for lenses and laser optics. A summary of the current commerical UV coating technology and specific applications is presented, with graphs of reflectance and transmission versus wavelength. A description of measurement equipment and methods is given.
