DEVELOPMENT OF MILLIMETER AND SUBMILLIMETER MASER DEVICES.

Abstract

The third reporting period has been devoted to the study of iron doped (Fe3+) zinc tungstate (Zn WO4) as a possible new quantum amplifier material. The solutions to the spin Hamiltonian have been obtained so that identification of energy levels is possible, and a computer program for the solution of radiation-induced transition probabilities has established. Since the dielectric constant of the zinc tungstate is considerably lower than that of the materials used previously, it has been necessary to make several changes in the experimental apparatus. Several pumping techniques, including the five level technique, will be investigated in zinc tungstate. During this period, operating points were chosen from the computer solutions of the Hamiltonian. (Author)
