title: Collapse of optical pulses.
abstract: Under the combined effect of diffraction, anomalous dispersion, and nonlinear refraction, an optical pulse can collapse simultaneously in time and space. Such a collapse could yield short pulses with extremely large optical fields. Light bullets-pulses that propagate without change in space or time-are also possible. The condition for such a collapse and possible experiments are discussed.
