ABSTRACT Compensation of thermally induced birefringence directed toward compensation of depolarization and bifocusing in laser rods is treated with simple beam transfer matrices. When we apply a 90-deg polarization-rotating element to a resonator, the radial and the tangential eigensolutions of the resonator change significantly. The effect of this alteration on the resonator ’s stability is investigated in detail. The outcome is used to design a single- and double-rod resonator resulting in 53 W with an M2 ~ 1.5 and 182 W of output power with an M2 ~ 1.2, respectively.
