Abstract
The influence of ionization effects on high-order harmonic generation in a gas-filled hollow fiber is theoretically analyzed. Due to the ionization-in duced self-phase modulation of the pump pulse in a hollow fiber filled with a weakly ionizing gas, the phase mismatch changes within the pump pulse, d ecreasing the overall efficiency of harmonic generation and making the harm onic-generation efficiency less sensitive to the gas pressure in the hollow fiber.
