DIVALENT RARE-EARTH IONS IN OPTICAL MASER MATERIALS

Abstract

The report concentrates primarily upon the systems BaClF:Ln2+ and ABF3:Ln2+ (where A = alkali-metal ion, and B = alkaline-earth ion), those compounds selected as best suited to our objectives. The problems were in three major categories: reduction of the rare earth from the normal trivalent to divalent, incorporation of the desired ion into the host with retention of the desired valence state, and the growth of single crystals of suitable optical quality. The first and third categories were satisfactorily solved in many cases, while the second was solved only to a limited extent. On the basis of these studies, one can specify in some detail the materials in which, and the conditions under which, this second aspect of the problem can be successfully solved.
