Acousto-optically induced unidirectional operation of a ring laser a feedback mechanism
A second mechanism for acousto-optically induced unidirectional operation of a ring laser has been identified and demonstrated experimentally. The mechanism involves feeding back the diffracted wave thus restoring to its original frequency and direction via a second diffraction from the travelling-wave acousto-optic modulator. Since the feedback resonance condition is different for the two counter-propagating waves of the ring laser they experience a loss difference which results in unidirectional operation via this method a very large loss difference can be achieved with negligible insertion loss.

Abstract
A second mechanism for acousto-optically induced unidirectional operation of a ring laser has been identified and demonstrated experimentally. The mechanism involves feeding back the diffracted wave thus restoring to its original frequency and direction via a second diffraction from the travelling-wave acousto-optic modulator. Since the feedback resonance condition is different for the two counter-propagating waves of the ring laser they experience a loss difference which results in unidirectional operation via this method a very large loss difference can be achieved with negligible insertion loss.
