Modification of polymers with UV excimer radiation from lasers and lamps
, 1994Photochemical dry etching and surface modification of various polymers, e.g. polymethylmethacrylate (PMMA), polyimide (PI), polyethyleneterephthalate (PET) and polytetrafluoroethylene (PTFE) were investigated with coherent and incoherent excimer UV ...

Laser safety with excimer lasers
International Laser Safety Conference, 1992Assuring the safe use of excimer lasers presents a variety of challenges to the laser experimentalist and the laser safety professional. At Los Alamos National Laboratory dozens of excimer laser systems are used for research in a wide variety of areas including spectroscopy, photochemistry, material interactions, inertial confinement fusion, optical ...

Excimer laser-induced vasoreactivity
European Heart Journal, 1993Earlier generations of excimer lasers, designed for industrial or non-cardiovascular medical applications, have been previously shown consistently to induce vasorelaxation of vascular smooth muscle in vitro. Such lasers were typically characterized by pulse durations of < or = 15 nanoseconds (ns).

The interaction of CO2, Nd:YAG, excimer and high-power diode laser (HPDL) radiation with the surface of an Al2O3/SiO2 based ceramic was found to effect significant changes in the wettability characteristics of the material.

Excimer laser surgery for keratoconus
Journal of Cataract and Refractive Surgery, 1998To determine whether there is increased risk associated with excimer laser surgery of primary keratoconus.Department of Ophthalmology, County Council Hospital, Ryhov, Jönköping, Sweden.Twenty-four eyes in 23 patients with keratoconus had photorefractive keratectomy (PRK) to reduce the steepness of the cone.

Until recently excimer lasers have been used almost exclusively in basic research, e.g. to pump dye lasers. However, this is not the only potentially useful application. The output of excimer lasers differs in one aspect quite drastically from all other known uv-light sources, namely fluence, which is number of photons per cm2 and sec.

Excimer Laser - Teil 2: Erste Erfahrungen mit dem Excimer Laser in Luzern
Klinische Monatsblätter für Augenheilkunde, 1992In the period between September 1990 and July 1991, 35 patients (46 eyes) were treated with the Excimer Laser. In 25 patients (34 eyes), a Myopia-Laser-Shaping was performed, one patient was treated for both myopia and astigmatism. In eight patients (10 eyes) correction of astigmatism was carried out.

Spatial coherence of KrF excimer lasers.
Applied Optics, 1992The spatial coherence and the beam divergence at 248 nm of a KrF excimer laser were obtained experimentally. These results are in good agreement with the theoretical calculations based on a simple pulse-laser model and the van Cittert-Zernike theorem ...

Investigation of the propagation characteristics of excimer lasers using a Hartmann–Shack sensor
, 2000For wave front distribution measurements of excimer laser radiation, a Hartmann–Shack wave front sensor with 40×30 subapertures and a field of view adapted to the lateral laser beam profile was utilized.
