The {ital ABCD} transfer matrix method is used to study the stability of a Z-fold cavity with two concave and two flat mirrors and a Brewster-cut crystal. Analytical solutions of stable regions of the cavity without thermal lensing have been obtained. The influences of thermal lensing on stability, beam waists, and astigmatic compensation are discussed. By use of a Ti:sapphire laser with a Z-fold cavity, lasing action was achieved in the predicted stable subregions that are accessible. {copyright} {ital 1996 Optical Society of America.}
