    Notes: Abstract As an outcome of a systematic study of excitation kinetics and fluorescence spectra concerning theD′(3π2u )→A′(3π2g ) transitions in homonuclear diatomic halogens and corresponding transitions in interhalogen molecules [1], this paper describes, for the first time, TEA laser action in the three halogen monofluorides ClF, BrF, and IF. Output energies in the mJ range were demonstrated in a fast TEA discharge arrangement at the wavelengths of 284.4, 354.5, and 490.8 nm for ClF, BrF, and IF, respectively. The results suggest parameter scalability and wavelength tunability.

    Notes: Abstract We have measured the Pt deposition yields on various substrate materials from Pt(PF3)4 in the case where a KrF laser irradiates the solid surface. The data imply that an ample amount of electrons is produced by the laser surface interaction and dissociative electron capture initiates the metal deposition. The metal atom release is completed by a concerted surface reaction at a reduced energy demand. This is evidenced by thermochemical considerations. A simple criterion is derived to estimate the attainable spatial resolution. Sudden melting and evaporation beyond a certain layer thickness interferes with the deposition process. This is in accord to a model given, based on a poor thermal contact at the platinum substrate interface. The results may help to optimize uv laser induced metal deposition with respect to purity, adherence and structure.
