Abstract
An unstable resonator system is controlled in polarization by the use of a compound resonator in which the parent resonator is coupled to a polarization control leg by an aperture that passes a small portion of the output beam into a polarization control element and returns a polarized feedback beam mode-matched to the adjoint mode of the parent resonator.
