Compact Kerr-lens mode-locked resonators.
We present a comparison of compact three-element Ti:Al(2)O(3) laser resonator designs for enhanced Kerr-lens mode locking. We demonstrate a novel compact cavity design that uses an intracavity lens and show that nonastigmatic modes can signif icantly increase Kerr-lens action and achieve self-starting mode locking. A new mechanism for group-velocity dispersion that arises from the chromatic aberration of the intracavity focusing elements is also demonstrated.
