We present a comparison of compact three-element Ti:Al{sub 2}O{sub 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 significantly 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. {copyright} {ital 1996 Optical Society of America.}
