The development of narrow bandwidth tunable laser systems in the vacuum UV region of the electromagnetic spectrum and of new exptl. methods has recently enabled a significant improvement in the resoln. that can be achieved by photoelectron spectroscopy. Th ...
Crystalline diamond coatings and, increasingly, diamond-like amorphous carbon (DLC) films are used for tribological and protective layers for their hardness and chemical inertness. They are also under investigation for their electron emitting properties, w ...
The combustion (oxidn.) is studied of anthracene and xanthone in a lab. scale incineration reactor illuminated with beams from a KrF- and XeCl-excimer laser at 248 and 308 nm. The destruction and removal efficiency of this photon-assisted process is substa ...
Fiber gratings irradiated by CW-laser show a breaking strength and a lifetime performance similar to that of pristine fiber, on pulsed KrF-laser irradiation. In this paper we report on the mechanical reliability of fibers irradiated by UV light using the s ...
Single-pass Raman cells pumped by either a quadrupled Nd:YAG (266-nm) laser or a KrF excimer laser are studied. The Raman-active gases comprise H2, D2, or CH4, as well as a mixt. of them, with the addn. of He, Ne, or Ar. A parametric study, in which the St ...
The mechanical resistance of UV irradiated optical fibers has been investigated by dynamic fatigue tests. The intrinsic Weibull distribution of the pristine and chemically stripped fiber were almost identical. The high germanium doped fiber was homogeneous ...
The formation of H-aggregates as a function of solution, substrate and ambient variables is considered for the merocyanine dye 3-acetyl-5-12-(3-ethyl-2-benzothiazolydene) rhodanine. Colloidal semiconductor particles are shown to be a powerful tool to contr ...
Characterization of the mechanical and thermal properties of the high aspect- ratio, negative, UV resist, SU-S has been carried out. This resist allows for a broad range of thicknesses to be obtained with a single spin process. Standard exposure with a UV ...
We have measured an upper limit of 17 J/cm(2) for the threshold fluence for collision-fret CO2 laser IRMPD of silane by detecting the SiH2 product in its electronic and vibrational ground state. The threshold drops to similar to4 J/cm(2) when silane molecu ...
An all-fiber tunable filter device that uses a resistive fiber coating to directly heat an intra-core Bragg grating is presented. Bragg gratings were fabricated in a hydrogen-loaded standard telecommunication fiber by a KrF excimer laser with a fluence of ...
