capacity of hollow Bragg fibers, CW and pulsed sources.

Large-core hollow dielectric fibers have been recently in- vestigated to provide a guiding platform for high power ra.diation in a wide range of IR frequencies [l-31. Due to the absence of an absorbing material in the core, hollow fibers have been demonstrated to guide kilowatts of CW power at a designable IR wavelength. The power capac-
