Abstract
We show that extremely short uv and vuv pulses with a duration in the range of 1 fs can be generated by pulse compression using hollow waveguides filled with a gaseous Raman medium. The specifics of phase-amplitude modulation, the mechanism of pulse compression and physical limitations due to phase mismatch, velocity walk-off, and pump pulse changing as well as improvement by the use of pump pulse sequences and dispersion control are studied by analytical and numerical solutions.
