Abstract

It is well known that mode-locking abilities of Kerr-lens mode-locked lasers strongly depend on spatial cavity configuration. A variation of intracavity spacings provides a control for system’s discriminating strength that favors high-intensity radiation against a low-intensity one. So, it is necessary to adjust precisely the system near the boundary of the stability zone. There is a number of publication devoted to the optimal geometries of Kerr-lens mode-locked lasers, mainly, for z-fold four-mirror resonators. However, yet not the whole potential of optimization has been worked out. Also, the possibilities of other than four-mirror resonators, i.e. two- and three-mirror resonators were not addressed at all, except very few experimental works
