Analytical design for Kerr-lens mode locking of compact solid-state lasers

Abstract

Michael R. Wang. An analytical solution for soft-aperturing Kerr-lens mode locking (KLM) of compact non-astigmatic three-element resonators is derived using non-linear ABCD ray matrix method. It is directly applicable to any three-element resonator configuration. General properties of compact resonators and the dependence of the Kerr non-linear strength on the resonator parameters are discussed. Selection guidelines on non-linear crystal length, focal length of the focusing element, and other cavity parameters for effective KLM are provided. © 1998 Elsevier Science B.V. All rights reserved.
