Abstract
Ionic crystals are promising materials for testing XUV source in PLD (pulsed laser deposition) arrangement. In this investigation of LiF we use an incidence angle of 20o to study characteristics of ablation and laser-matter interaction under conditions similar as in the PLD arrangement.
Single-shot ablation threshold was determined. Also CaF2 was irradiated by XUV radiation and ablation threshold relative to LiF was determined.
Irradiated samples have been investigated by Nomarski (DIC-Differential Interference Contrast) microscopy and optical profiler (WLI-white light interferometry).
