Abstract

We report compression of low-power femtosecond pulses at $1.06\mu \mathrm{m}$ in a dispersion-decreasing holey fiber. Near-adiabatic compression of $130\mathrm{fs}$ pulses down to $60\mathrm{fs}$ has been observed. Measured spectra and pulse shapes agree well with numerical simulations. Compression factors of ten are possible in optimized fibers.
