Abstract:
A laser includes a traveling-wave ring-resonator in which one resonator mirror is a mirror of an interferometer arranged such that, when the interferometer is operated in an anti-resonant condition, the mirror has a greater effective reflectivity for clockwise circulation of light in the resonator than for anticlockwise circulation of light in the resonator. There is a difference between the clockwise and anticlockwise effective-reflectivity sufficient that lasing in the resonator is possible only in the clockwise direction.
