Book Description
Heavy metal fluoride glass materials are attractive for optical applications in the near ultraviolet through infrared wavelength regions. However, many compositions are relatively soft and hygroscopic, and possess low softening temperature (250°C-300°C). We have applied ion assisted deposition (IAD) techniques to deposit MgF2, SiO2 and Al2O3/SiO2 thin film structures on fluoride glass substrates at ambient substrate temperature (100°C). The coatings deposited using IAD improve the environmental durability of the fluoride glass and appear to have reasonably good optical charateristics; without application of IAD, the deposited coatings are not durable and have poor adhesion.

Book Description
The effects on the properties of Ta2O5, Al2O3, SiO2 and HfO2 single- and multi-layer optical coatings deposited using ion assisted deposition (IAD) were investigated. IAD is a novel deposition technique which utilizes a separate ion source to direct a beam of ions at the growing film. A Kaufman ion source was used to provide a monoenergetic, neutralized beam of oxygen ions independent of the material evaporation process. The optical and physical properties, as well as laser induced damage threshold (LIDT) values, were studied for coatings bombarded with 200, 300, 500 and 1000 eV oxygen ions at values of current density from 0 to 200 microAmp/sq cm. IAD was successfully applied to deposit coatings at low temperature on heavy metal fluoride (HMF) glass substrates. The coatings deposited using IAD were hard and dense. The IAD coatings improved the durability and abrasion resistance of the HMF glass substrates. The results of this investigation show that IAD can be used to improve the optical and physical properties of optical coatings.
