Laser-induced damage thresholds for microparticle carbon-contaminated λ/2 coatings. Lowest damaging and highest survived irradiances are plotted for each material. Silica λ/2 coatings (9 eV) were not damaged in testing. The dashed line represents thermally generated free carrier induced breakdown as predicted by our model.
