    "abstract": "By use of an imaging spectrometer we map the far-field ($\\theta-\\lambda$)\nspectra of 200 fs optical pulses that have undergone beam collapse and\nfilamentation in a Kerr medium. By studying the evolution of the spectra with\nincreasing input power and using a model based on stationary linear asymptotic\nwave modes, we are able to trace a consistent model of optical beam collapse\nhigh-lighting the interplay between conical emission, multiple pulse splitting\nand other effects such as spatial chirp.",
