Description

Single-layer ZrO/sub 2/ coatings were deposited in an ultrahigh vacuum system by two techniques: laser evaporation (utilizing a 100-W, continuous wave, CO/sub 2/ laser) and electron-beam evaporation. Substrate temperatures were maintained at either 1500C or 2500C with backfill oxygen pressures between 0 and 5x10/sup -5/ torr. The coatings were analyzed by Auger Electron Spectroscopy to determine stoichiometry and to provide information on the nature and level of impurities. The refractive indices for the coatings were determined by ellipsometry at 6328 A. Selected coatings were damage tested at 531 nm. This report discusses the influence of backfill pressure, substrate temperature and evaporation technique on thin film properties and compares the results obtained by Auger and ellipsometric analyses. Also presented is a comparison between films prepared under high vacuum and ultrahigh vacuum conditions
