Phase-conjugate resonators with intracavity amplitude perturbations

A numerical analysis was carried out to compare the performance of phase-conjugate resonators with that of conventional resonators in the presence of amplitude perturbations. It is shown that, for low levels of perturbation, phase-conjugate resonators display lower diffraction losses and give better phase front matching at the conventional mirror surface. As the level of the disturbance is increased, these superior properties of phase-conjugate mirror resonators are diminished.
