Abstract
Laser induced damage in optical coatings is a complicated problem, which is attributed to a lot of factors, including environment parameters, laser parameters and thin film production parameters. Among the three factors, production parameters interest us most. We produce a series of samples with different roughness levels of the substrates, thin film material and vacuum environment within the chamber, etc. Using 1.06 micrometers Nd:YAG laser as our test laser, we make 1- on-1 laser damage test to these samples. Some interesting phenomena are found. We calculate the laser induced local heating within the thin film multilayers, and make analysis to the experimental phenomena. Conclusions are given.
