Optical Hole Burning of Materials for Frequency Domain Optical Storage and Processing
Abstract
Over the report period, an optical laboratory for characterization materials for frequency domain optical storage was upgraded. Spectral and spectral hole burning properties were studied for several free-based and metallo-naphthalocyanine derivatives in polymer hosts. These materials exhibit a strong 0-0 absorption band and persistent hole burning in the region 800 nm. Hole burning parameters were determined for eight materials; in particular, the hole burning kinetics was analyzed and the quantum efficiencies were determined to be between 0.1% and 1%. Holograms (data pages) in the transmission geometry were successfully recorded in the materials studied using single frequency laser diodes. A photoluminescence of five natural diamonds (type Ia) implanted with Xe ions with dose range 1x10(exp 13) - 5x10(exp 14) /sq cm was investigated as a function of thermal annealing at temperatures between 300 and 1400 C.
