Abstract
A high-power oscillator which uses a quasi-optical ring resonator to prov the feedback required for oscillation allows energy to travel in one direction only within the resonator and suffers little loss of energy during operation. The oscillator is built by inserting an array of amplifiers, tuned to a desired frequency, into the quasi-optical ring resonator formed by three reflective mirrors. The mirrors are spaced such that the total loop phase shift is equal to an integer multiple of 360 degrees at the desired frequency and, by proper selection of the amplifiers, the loop gain is set to be greater than or equal to one.
