Abstract
An improved ring laser system having mutual coupling between two or more ring laser resonators employs a two-step coupling process, in which coupling power is coupled into the adjoint forward mode of an adjacent resonator, from which it diffractively couples to the forward mode. A portion of forward-mode power is coupled into the adjoint reverse mode from which it diffractively couples to the reverse mode within each resonator. A portion of this reverse mode power is used to coupled into other resonators. A complementary configuration employs forward-mode radiation as the coupling radiation.
