Abstract
The decrease of laser-induced damage threshold (LIDT) when exposed with high number of laser pulses is a well-known phenomenon in dielectrics. In the femtosecond regime this fatigue is usually attributed to the accumulation of laser-induced lattice defects. Little is known about the accumulation mechanisms in oxides used for dielectric coatings. In this work, S-on-1 laser-induced damage threshold test was combined with time-resolved digital holography in order to investigate laser-induced lattice defects in Nb2O5 single layer. The results provided insights into the current understanding of accumulation of laser-induced defects.
