Book Description
The principal objective of this research is to investigate, both theoretically and experimentally, cooperative optical transitions in solids, with the goal of finding efficient systems for the generation of upconverted stimulated emission. Of interest also are new optical pair effects and studies of the resonance fluorescence and coherence on cooperative transitions. In the third year of the program, significant advances were made in the experimental aspects. Measurements of upconversion dynamics were made in erbium-doped crystals and in a fluorozirconate glass. Upconversion laser operation was observed at two visible wavelengths in YLiF4:Er 5% and pumping pathways identified. Spectral and lifetime studies are reported for promising new laser host materials.
