TAS 57 3600::TAS HOLLOW OPTICAL FIBERS FOR OPTICAL PARAMETRIC GENERATION
Abstract
Hollow optical fibers have been developed over the past 20 years in Bath. The most recent generation are based on an anti-resonant guidance mechanism and have presented a step change in both performance and manufacturability. Performance in the mid-infrared is particularly striking. The very first fibers offered a propagation loss of 30 dB/km at 3.2 ?m wavelength, which is more than 5000 times less than the attenuation of the silica glass from which the fiber was made, and is amongst the lowest attenuation of any fiber made of any material at this wavelength. These advances in mid-infrared hollow optical fibers as well as their applications for mid-infrared lasers show promise for extension to optical parametric generation in gases for AFRL research. The proposed project will combine development, fabrication and characterization of hollow optical fibers in the CPPM for controlling the phase matching of near-degenerate parametric generation. If this is successful, fibers will be developed for tunable non-degenerate processes targeting conversion of near infrared diode laser into mid-infrared wavelengths.
