Abstract
In this work tests for determination of ablation thresholds of various ceramic materials for pulsed laser irradiations at wavelengths of 355 nm and 1064 nm in vacuum are presented. For comparison tests with copper and aluminium are also reported. The ablation process was monitored insitu by long-distance microscopy. The morphology of ablation spots was exsitu inspected by scanning electron microscopy. Furthermore, the redeposition of potentially released particles on optics in the vicinity to the target was examined.
