Proof of the Feasibility of Coherent and Incoherent Schemes for Pumping a Gamma-Ray Laser
Abstract
Recent approaches to the problem of the gamma ray laser have focused upon upconversion techniques in which metastable nuclei are pumped with long wavelength radiation. At the nuclear level the storage of energy can approach tera-Joules per liter for thousands of years. This report focuses upon a variety of new technologies to demonstrate feasibility benefitting from the strong momentum realized already along the approach to incoherent pumping, most continued to advance the development of the nuclear analog of the ruby laser. A unique type of Compton spectrometer was brought into service during this reporting period. The greatest breakthrough was realized along the more complex approach of coherent pumping. There it is intended to mix the quantum properties of long-lived isomeric states with those of freely radiating nuclear levels.
