Losses of phase-conjugate resonators: directional behavior in aberrated multiaperture cavities

Abstract
The directional behavior of power losses in aberrated multiaperture optical resonators with one or two phase-conjugate mirrors is investigated through integral equations and the reciprocity theorem. In a resonator with one phasecohjugate mirror, the losses of the mode traveling from the conventional mirror to the phase-conjugate mirror are shown to be larger than the losses of the counterpropagating mode. In a resonator with two phase-conjugate mirrors, the losses along each direction are found to be equal.
