The Fox–Li iterative method [Bell Syst. Tech. J. 40, 253 (1961)] is used to find solutions for a three-dimensional phase-conjugate resonator with a saturated gain, a random aberrator, and a pinhole spatial filter. The performance of such a resonator is excellent for resonator Fresnel numbers as small as 5 and for phase-error standard deviations as large as 2π. The use of a spatial filter to control the transverse mode shape is demonstrated.
