100 /spl mu/J and 5.5 W Yb-fiber femtosecond chirped pulse amplifier system

Summary form only given. We have demonstrated the first all-fiber high-energy/power coherent pulse amplifier system based on Yb-doped fibers. Microjoule femtosecond pulses have been obtained at MHz-repetition rates. Achieved pulse durations and output powers constitute a significant improvement over the corresponding characteristics of Er-doped fiber amplifiers.
