Abstract : This program is intended to explore cooperative interactions among rare earth dopants in dielectric solids, with upconversion lasers and nonlinear optical applications in mind. The focus is on fundamental studies of multi-atom upconversion and avalanche processes rather than multiphoton upconversion for new short wavelength lasers. Because of significant potential applications in the areas of short wavelength sources, optical memories, communications, and displays it is important to improve our understanding of cooperative dynamics in regard to their optical and spatial coherence, temporal evolution and relaxation mechanisms.
