1. A method of operating a mode-locked laser comprising the steps of:

  • propagating the intracavity laser pulse through a first segment having normal group velocity dispersion;

    propagating the intracavity laser pulse through a second segment with normal group velocity dispersion and doped with an element that produces gain; and

    propagating the laser pulse through a third segment having anomalous group velocity dispersion and negligible nonlinearity such that the laser pulse width increases monotonically in the normal group velocity dispersion segments and decreases monotonically in the net anomalous dispersion segment as it propagates around the cavity.
