Metal Vapor Laser Contaminant Study.

Abstract

Contaminants evolved during lead and copper vapor laser operation are identified. The principal long term source is the hot high density alumina discharge tube. Procedures for decontamination down to 10 to the -6 mm partial pressure are described. Such decontamination is shown to be necessary for proper wick function and sealed-off operation. In conjunction with this work, a model has been demonstrated that relates metal vapor containment time to wick dimensions and a new sealed-off laser design has been successfully tested. (Author)
