Experimental and theoretical investigations of large bandgap LiF dielectrics ablation threshold induced by 7 ps 13.9 nm XRL pulses were performed. LiF crystal threshold is about 1600, 210 and 8 times smaller compare with LiF crystal thresholds measured previously for ns and fs visible lasers and ns 46.9 nm soft XRL, correspondently.
