摘要：

220-fs pulses with energies of similar to 100 muJ have been generated by use of two different configurations of diode-pumped Yb-fiber chirped-pulse amplification systems. Energy scaling was demonstrated with 25-mum-core diameter fibers, in which stable diffraction-limited output (M-2 similar to 1.1) was achieved. A two-stage fiber-amplifier system produced average powers of up to 5.5 W at similar to1-MHz pulse-repetition rate. A double-pass configuration provided 53-dB gain in a single Yb-fiber amplifier stage, thus eliminating the necessity for multiple amplification stages as well as the need for using polarization-preserving fibers.
