Description / Table of Contents:
The generation of THz radiation from ionizing two-color femtosecond pulses propagating in metallic hollow waveguides filled with Ar is numerically studied. We observe a strong reshaping of the low-frequency part of the spectrum. Namely, after several millimeters of propagation the spectrum is extended from hundreds of GHz up to $sim 150$ THz. For longer propagation distances, nearly single-cycle near-infrared pulses with wavelengths around 4.5 $mu$m are obtained by appropriate spectral filtering, with an efficiency of up to 0.25 %.
