Daniault, D. Gaponov, M. Hanna, S. Février, P. Roy, F. Druon, P. Georges, M. Likhachev, M. Salganskii, M. Yashkov] We report on high power amplification of femtosecond pulses in 40-μm core diameter Yb-doped photonic bandgap Bragg fibers. The robustness to bending and transverse spatial behavior of these fibers is analyzed through simulations. The fibers are used in both stages of a moderately stretched (150ps) femtosecond chirped pulsed amplification (CPA) system. Acompressed average power of 6.3W is obtained using a low-index polymer-coated Bragg fiber with excellent beam quality and high efficiency, in agreement with numerical simulations. The use of an air-clad Bragg fiber allows us to scale the output power to 47W at a repetition rate of 35 MHz. This experiment demonstrates the great potential of Bragg fibers to increase the mode area and the power of practical bending-tolerant femtosecond fiber systems. Springer-Verlag, 2011 Daniault L.
