    "abstract": "Nonstationary pulse regimes associated with self modulation of a Kerr-lens\nmodelocked Ti:sapphire laser have been studied experimentally and\ntheoretically. Such laser regimes occur at an intracavity group delay\ndispersion that is smaller or larger than what is required for stable\nmodelocking and exhibit modulation in pulse amplitude and spectra at\nfrequencies of several hundred kHz. Stabilization of such modulations, leading\nto an increase in the pulse peak power by a factor of ten, were accomplished by\nweakly modulating the pump laser with the self-modulation frequency. The main\nexperimental observations can be explained with a round trip model of the fs\nlaser taking into account gain saturation, Kerr lensing, and second- and\nthird-order dispersion.",
