Induced gain in Cr,Nd:GSGG by pulsed X-ray radiation

Brannon, P.J.

A nonnalized X-ray induced gain coefficient, 1.48 x 10{sup -3} cm{sup -1}/krad, has been determined for Cr,Nd:GSGG. Hermes III, a 20 ns, 2 MeV X-ray source, is used to irradiate the sample. Doping levels of 1 x 10{sup 20} and 2 x 10{sup 20} /cm{sup 3} respectively, for Cr and Nd are used. A proposed heuristic model in which excited Gd transfers its excitation to Cr which then transfers its excitation to Nd is described.
