A Preliminary Study of Krypton Laser-Induced Fluorescence

Abstract

There is growing interest in the use of krypton as propellant for electric propulsion as a lower cost replacement for xenon. This study examines the potential applications of laser-induced fluorescence as a plasma diagnostic technique for Kr I and Kr II. Candidate electronic transitions are examined to determine their suitability for successful routine application of laser-induced fluorescence. Criteria considered include lower state populations, optical accessibility, existence of nonresonant fluorescence transitions, and fluorescence branching ratios. Using these criteria, one transition for each Kr 1 and Kr II are identified for future development.
