    "abstract": "We study the temporal and spatial dynamics of the large amplitude and\nfrequency modulation that can be induced in an intense, few cycle laser pulse\nas it propagates through a rapidly ionizing gas. Our calculations include both\nsingle atom and macroscopic interactions between the non-linear medium and the\nlaser field. We analyze the harmonic generation by such pulses and show that it\nis spatially separated from the ionization dynamics which produce a large\ndynamical blue shift of the laser pulse. This means that small changes in the\ninitial laser focusing conditions can lead to large differences in the laser\nfrequency modulation, even though the generated harmonic spectrum remains\nessentially unchanged.",
