Abstract

Lifetime enhancement of optical components is still one of the major topics in space based laser applications. In this work a novel multichannel test setup for basic research of laser-induced contamination (LIC) phenomena is introduced. LIC growth dynamic was analysed in dependence on laser fluence and repetition rate. Uncoated and anti-reflective coated fused silica optics were investigated. The coatings were produced by two different processes: e-beam deposition and magnetron sputtering. The influence of coating morphology and composition on LIC growth is discussed.
