Femtosecond seeding of a Tm-Ho fiber amplifier by a broadband coherent supercontinuum pulse from an all-solid all-normal photonic crystal fiber

Summary form only given. In this paper we present for the first time the seeding of a Tm-Ho:fiber amplifier by a broadband coherent SC pulse generated in all-normal dispersion (ANDi) fiber. This approach has two significant advantages: (i) excellent coherence is maintained for a wide range of pump pulse and fiber parameters, and (ii) the SC consists of a single ultrashort pulse in the time domain, i.e. it does not break up into individual solitons. Hence, it is ideally suited for seeding fiber amplifiers whose gain bandwidth overlaps with any part of the SC bandwidth.
