Astigmatism and gain guiding in Kerr-lens mode-locked lasers.
The effects of astigmatism and the radial variation of the gain on Kerr-lens mode-locking (KLM) are studied with the help of an extended ABCD matrix formalism. A dramatic broadening of the allowed cavity parameter region is predicted that permits KLM in almost the whole stability region. The cavity design for KLM with an aperture differs significantly from the design for KLM without an aperture, because of the saturable diffraction loss.
