Abstract

We study soliton-effect pulse compression in the single-cycle region in dielectric-coated metallic hollow waveguides filled with a noble gas exploiting the broad region of anomalous dispersion in these waveguides. We predict the compression of a 20-fs pulse to a FWHM duration of 1.7 fs with an energy of 6 muJ and study the physical factors determining the limitations on shortest pulses in the single-cycle regime.
