Modeling the subpicosecond pulse compression in the vacuum ultraviolet and the extreme ultraviolet

A. B. Blagoeva, S. G. Dinev, A. A. Dreischuh


A method for pulse compression to the subpicosecond range in the VUV and the XUV is investigated theoretically. The induced phase modulation on a signal by a pump pulse near two-photon resonance in inert gases is analyzed, including group-velocity dispersion, pulse walk-off, initial delay, shift of the signal peak, and linear and nonlinear chirp rates for Gaussian and hyperbolic secant pulses. A reasonable agreement is found with the theoretical and experimental results of other authors.
