The impact of O/Si ratio and hydrogen content on ArF excimer laser ablation of fused silica [PDF]
Journal of the European Optical Society-Rapid Publications, 2014 The impact of stoichiometry and hydrogen content on the ArF excimer laser ablation characteristics of fused silica is investigated. Near-surface substoichiometic SiOx with X < 2 diminishes the ablation threshold as a result of increased absorption.

Concentrator of laser energy for thin vapour cloud production near a surface [PDF]
, 1998 A novel scheme is presented for production of a thin ($100$ cm$^2$) by pulsed laser ablation of a solid surface. Instead of dispersing the laser energy uniformly over the surface, a modified Fabry-Perot interferometer is employed to concentrate the laser
