Mode locking of Ti:Al2O3 lasers and self-focusing: a Gaussian approximation
Abstract
An ABCD matrix model is presented showing that self-focusing in the laser rod leads to modifications of the Gaussian beam parameters in CW-pumped Ti:Al2O3 lasers. Stabilization of self-mode-locking should result from these beam perturbations. Experimental measurements of beam modifications supporting this model are presented. The role of gain guiding is studied, and the limitations of the model are discussed.
