Coupling of unstable resonators in circulant arrays is considered, in which the array is invariant with respect to the interchange of any pair of resonators. A proof-of-concept experiment performed with six series coupled CO(2) lasers with confocal unstable resonators is reported. Adjoint coupling was used with two symmetrically placed coupling apertures in each resonator output. The results of measurements of the locking range, supermode content, and beam quality for standing wave and ring resonator arrays are presented and interpreted using simplified models. It is pointed out that adjoint coupled unstable resonators provide a modular scaling configuration with modest phase-locking length control requirements.
