Abstract
We report on the laser damage resistance of ion beam-sputtered oxide materials (Al2O3, Nb2O5, HfO 2, SiO2, Ta2O5, ZrO2) and mixtures of Al2O3-SiO2, Nb2O 5-SiO2, HfO2-SiO2, Ta 2O5-SiO2, and ZrO2-SiO2, irradiated by single 500 fs pulses at 1030 nm. Laser-induced damage threshold (LIDT), refractive index, and bandgaps of the single-layer coatings are measured. For pure oxide materials a linear evolution of the LIDT with bandgap is observed. The results are in accordance with our simulations based on photo-ionization and avalanche-ionization. In the case of mixtures, however, deviations from the previous behaviors are evidenced. The evolution of the LIDT as a function of the refractive index is analyzed, and an empirical description of the relation between refractive index and LIDT is proposed.
