Abstract : This paper contains a discussion of experimental annealing techniques designed to relieve mechanical strain within Gd3Ga5O12 crystals. In addition, the techniques and data used for the measurement of excitation spectra, fluorescent lifetimes, large-angle scattering, and fluorescence linewidths for several neodymium-doped glasses are discussed. The analysis of data taken for the room-temperature ruby R sub 1 linewidth revealed instrument broadening effects, and various approaches to this measurement were examined. This report also mentions an optical walkie-talkie device, but details of the work on this instrument are deferred to a later report. Descriptions of the various optical components fabricated and delivered to the customer during the second quarter are also included. Plans for experimental work to be conducted during the next quarter are given. (Author)
