1 March 1974 Diagnostic Arc Studies With Ruby Laser
Author Affiliations +
A dye-switched TEM:00 ruby laser has been employed for two types of diagnostic studies of short, unstable, high-pressure dc arcs in noble gases. Holographic interferometry mea-sures gas density distributions, and a simple fringe-projection technique gives time-resolved contours of the agitated molten anode surface. A recently-developed mathematical technique permits avoidance of speckle problems in the holography by use of collimated scene beams, while greatly reducing the labor involved in gathering experimentally and analyzing numerically the data needed to determine asymmetric density distributions. Because fringe projection revealed intriguing unexpected details of arc-anode interface behavior, ideas are presented for further elaboration of the technique.
