Abstract

We have investigated the role of native point defects in the laser damage behavior of amorphous thin films of Sc₂O₃ deposited by ion beam sputtering. Through systematic characterization and detailed modeling we show that native defects influence the 1-on-1 laser induced damage threshold fluence of the Sc₂O₃. This effect, as shown by the model and confirmed by experiments, is pulse duration dependent.
