LASER ACTION BY ELECTRON BEAM PUMPING: STATE OF THE ART, TECHNICAL CONSIDERATIONS, AND GUIDE FOR EXPERIMENTS.
Abstract
This report relates to laser action by electron beam pumping. Results of a literature survey conducted on the state of the art up to August, 1964, are presented. The papers chosen for review were selected to show the type of work being performed with electron beam pumping, and to form the basis for feasibility conclusions. Calculations intended to provide starting points for future work are also given. These include calculations of ion density in ruby, electron beam density, quantum efficiency, and critical fluorescent power. Also presented is the original data from which a family of curves is generated to predict electron penetration depths into materials of known density. The report concludes with a list of equipment for setting up an electron gun apparatus and a conceptual sketch of a compact, electron beam laser device. The conclusion reached was positive feasibility. This has since been verified. In addition, because of the advantages pointed out in the report, interest in the technique of electron beam pumping has been continually increasing. (Author)
