Acousto-optic modulators as unidirectional devices in ring lasers.
Acousto-optic modulators can act as optical diodes and force the unidirectional single-axial-mode operation of ring lasers. We explain this effect in terms of the Doppler shift of the scattered light beams and present results of experiments in support of this theory.
