With the help of the self-consistent ABCD matrix method the fundamental TEM{sub 00} mode of a four-mirror cavity with active rod and hard aperture is analyzed. Cavity parameters ranges with the small diffraction losses at hard aperture and the decreased diffraction losses for the increased mode intensities due to self-focusing in active medium are shown immediately for practical Kerr-lens model-locked (KLM) Ti:sapphire lasers. To do this the authors have obtained the generalized solution of the wave propagation equation in self-focusing medium for arbitrary curvature radius of phase front of coincident gaussian beam. The fluctuation model of self-mode-locked lasers is used to demonstrate the generation of a stable ultra-short pulse train by the system under constant pumping for the obtained cavity parameters.
