Abstract

Sol-gel derived and base-heat treated antireflective (AR) coatings with good abrasive/scratch resistant performance have been investigated and developed. The comparison of abrasive/scratch resistant property of the AR coatings from this method to that from other methods demonstrated that the base-heat treated AR coatings have still more abrasive/scratch resistant ability. After more than 30 times of drag wipe and 1000 times flashlamp glow discharges of 300 microsecond(s) duration and 15 J/cm² for each discharge, the AR- coatings indicated no visible crazing or peeling. In the mean time, more than 6% transmission gain related to the spectrum of Nd⁺³ absorption can be obtained and maintained.
