An argon laser is used to induce Laser Chem. Vapor Deposition (LCVD) of platinum using platinum bihexafluoroacetylacetonate as precursor. The process can be photolytic or pyrolytic depending on the laser power used. These processes are studied by recording ...
The measurement of the tokamak plasma ion temperature can be obtained by collective Thomson scattering. This method requires a far infrared laser to achieve useful spatial resolution for typical tokamak plasma parameters. The very low Thomson scattering cr ...
The present work is part of a feasibility study to investigate the excimer laser photon-assisted thermal decompn. of anthracene at 248 nm. The principle is to combine UV photons of an appropriate light source and heat in an incinerating reactor at modest t ...
Laser-induced CVD has been used to produce Pt lines on pyrex glass substrates by means of platinum bis(hexafluoroacetylacetonate) as precursor. The effect that writing speed has on the line geometry and resistivity was studied, as well as the influence of ...
Laser generated defects in (Al,Ga) As have been investigated by photochemical wet etching and TEM measurements. Photoetching reveals a 500 nm wide zone in the center of the processed area where according to laser power either a luminescent or a nonradiativ ...

A model which takes into account the main phenomena occurring during the laser-cladding process is proposed. For a given laser power, beam radius, powder jet geometry, and clad height, this model evaluates two other processing parameters, namely, the laser ...
A laser-induced depostion technique is used to produce platinum interconnection lines for microelectronic applications. The influence of the laser power as well as the vapor pressure of the precursor upon the geometry, the morphol. and the line resistivity ...
In this paper we present briefly two possible approaches for modelling the laser cladding process. The first approach is 2D and consists in finding the shape of the molten pool given the fraction of the laser power which is available at the surface of the ...
SF6 in a free jet was vibrationally excited by a continuous-wave CO2 laser. The subsequent energy transfer processes, in which vibrational energy is degraded, lead to changes in the beam's spatial, velocity and cluster-size distributions. These changes wer ...
The deposition of Ga on quartz substrates by photodissociation of trimethylgallium has been investigated. Light from a frequency doubled Ar-ion laser beam (257.2 nm) was focused onto quartz substrates. The Ar-ion laser was operated under CW or mode-locking ...
