TLDR
In this paper, a simplified hybrid excimer-dye laser system is described, capable of generating sub-picosecond pulses at most of the excimer laser wavelengths, and the effect of operational conditions of different parts of the system and of the compressor on the spectral and temporal characteristics of the output pulse is studied.About:

J. Ihlemann,B. Wolff,P. Simon +2 more
TL;DR: Ablation of fused silica using standard excimer lasers (20-30 ns pulse duration at 193, 248, and 308 nm) and a short pulse laser system (500 fs at 248 nm) is reported in this article.

Surface modifications induced by ns and sub-ps excimer laser pulses on titanium implant material
TL;DR: X-ray photoelectron spectroscopy analysis of the laser-polished titanium surface revealed that laser treatment led to a decrease of the surface contamination and in thickening of the oxide layer, which resulted in effective smoothing, as measured with atomic force microscope.

Machining of submicron structures on metals and semiconductors by ultrashort UV-laser pulses
P. Simon,J. Ihlemann +1 more
TL;DR: Ablation of submicron structures on copper and silicon by short ultraviolet laser pulses (0.5-50 ps, 248 nm) is presented in this article. But the results of the ablation are limited.

Negative group-velocity dispersion using refraction
TL;DR: In this article, it was shown that a negative contribution to the group-velocity dispersion always accompanies angular dispersion and structures, such as slabs and prisms, that use this contribution to provide adjustable group velocity dispersion.
