Paper Abstract

Ion beam sputtered (IBS) coatings offer some distinct advantages over electron beam deposited (e-beam) coatings, namely environmental stability and extremely low total losses. Initial IBS coatings had excessive stress and low laser damage thresholds. For these reasons, a study was initiated to examine potential laser damage thresholds and stress of IBS coatings. A material study was conducted of IBS coatings produced in industry, and a variety of design techniques were explored to increase laser damage thresholds. A post annealing process and backside coatings were developed to reduce the coating stress.
