Abstract

Crystalline sesquioxide films (Sc₂O₃, Y₂O₃, Lu₂O₃) produced by pulsed-laser deposition were examined for laser damage resistance with pulses of 500 fs duration, at a wavelength of 1030 nm and at a 10 Hz repetition rate. Comparable tests were performed with amorphous magnetron-sputtered thin films (SiO₂, HfO₂, Nb₂O₅). We found the laser-induced damage thresholds of the sesquioxides are close to those of HfO₂ in the multi-pulse test regime. The results are the basis for designs of damage resistant re ective components used in ultrashort-pulse lasers.
