Dispersion-managed all-fiber chirped-pulse amplifier yielding high-power clean sub-500-fs pulses at 1.5 #x03BC;m

摘要

All-fiber chirped-pulse amplification based on a large-mode-area Er:Yb-doped photonic-crystal fiber is presented. A dispersion-variable hybrid fiber stretcher compensates the peculiar dispersion of the hollow-core photonic-bandgap fiber compressor yielding transform-limited 440-fs pulses with 1-W average power.
