Yen, W M

We summarize the progress we have achieved in several areas central to the mission of this grant. These include advanced in our understanding of the nature of relaxation processes which affect the optical linewidths and in the analysis of optical energy transfer accompanied by spectral diffusion in inorganic glasses. We have also developed and demonstrated two new laser spectroscopic techniques, Saturation Resolved Fluorescence (SRF) and Dilution Narrowed Spectroscopy (DNS), which have contributed to our understanding of transparent activated ceramics and other areas of interest. We continue by discussing additional work we propose to undertake, inclusive of on-going activity and certain interesting new initiatives. The bulk of the proposed work is, naturally, based on the experimental accomplishments of the present effort; while the new initiatives center on the opportunities new techniques, such as SRF and DNS, have opened up and on the availability of new optical materials, often with restricted dimensions. 39 refs., 7 figs.
