ABSTRACT
Knowledge of the Hg(3P1) spatial distribution in Hg rare gas low pressure discharges is important for understanding radiation transport, and aids in the formulation of discharge models for fluorescent lamps. We report on a novel single laser, two intersecting beams technique, which, for the first time, yields pinpoint information on the radial density profile of excited state mercury in the discharge positive column. Advantages over conventional single beam absorption are discussed, and preliminary data for a discharge containing one isotope (198Hg) of mercury and 2.5 Torr argon are presented.

    Collective Thomson scattering at 266 nm is used to obtain spatially resolved, two-dimensional electron density, temperature, and radial drift profiles of a collisional laser plasma (critical density, nc =1×1021 cm-3). An ultraviolet diagnostic wavelength minimizes the complicating effects of...

    Numerous nanophotonics applications involve the spatial confinement of the electromagnetic field to a length scale comparable to the optical wavelength, such as in photonic crystal (PhC) cavities or defects or in microlasers. First, we review a recently proposed, novel optimization scheme for...

    In keyhole welding, welding quality is closely related to the stability of the keyhole, which is primarily determined by keyhole geometry during the welding process. Three essential attributes to describe the simplified three-dimensional keyhole shape include keyhole size, penetration depth, and...

    Interpolation by translates of "radial" basis functions F is optimal in the sense that it minimizes the pointwise error functional among all comparable quasi-interpolants on a certain "native" space of functions ?[SUBF]. Since these spaces are rather small for cases where F is smooth, we study...
