title: Generation of multiwatt, broadband continua in holey fibers.
abstract: We demonstrate that 2-W average-fpower 310-nm-wide continua can be generated in holey fibers by use of a novel 6-W pump source at 770 nm. The pump source is demonstrated by use of the 64% efficient quasi-phase-matched second-harmonic generation of a seeded 10-W erbium fiber amplifier in periodically poled KTP. Nonlinear contributions to generation of high-power continua in holey fibers are identified and analyzed.
