Paper Abstract

We simulate pulse compression mechanism based on a near-two- photon-resonance (NTPR) transition contribution to the nonlinear refractive index of atomic Noble gas filled hollow wave-guides. The negative refractive index contribution in the normal dispersive gas waveguide, plays a similar role as in the case of soliton compression with positive Kerr non- linearity and anomalous dispersion in optical fibers. The self pulse compression to approximately 15 fsec can be achieved at moderate peak powers for 100 fsec pulses in the spectral range 100-245 nm. We present simulated data concerning pulse and spectral shapes for xenon as a case study. The total throughput of the propagated pulse energy is > 90 percent, mostly determined by the linear attenuation of the hollow wave-guide propagation mode while two photon absorption and the corresponding enhanced three photon photo-ionization does not significantly reduce the pulse energy.
