Paper Abstract

Hafnia is one of the most utilized high-index materials in thin-film multilayer coatings for high-power lasers. It is well established that in the HfO2/SiO2 multilayers for 351 nm, nanosecond-pulse applications the damage is driven by the nanoscale absorbers localized in the hafnia layers. In this work, damage-crater formation thresholds and morphology are investigated for the undoped HfO2 monolayer films and films containing isolated gold nanoparticles of 2- and 5-nm average diameter. Atomic force microscopy is used for characterization of the damage craters produced by 351-nm, 0.5 ns laser pulses. This comparative study of crater-geometry variation with laser fluence for doped and undoped films allowed the estimation of properties of the intrinsic absorbing defects in the hafnia films.
