Absorption-influenced Laser Damage Resistance of Ta 2 O 5 Coatings

Abstract
Results from experiments on laser-induced damage and absorption of evaporated Ta2O5 quarter-wave single-layer films are presented at u = 530 nm and 1060 nm, respectively. The absorption measurements were carried out by laser calorimetry. Emphasis is layed on the lack of correlation between absorption and laser damage in the 10m3 range of absorption itself and the statistical-like behaviour of the damage threshold.
