Abstract

Summary form only given. In a mode-locked ring laser the counterpropagating pulses are used to measure nonreciprocal phase differences of 10/sup -6/. When the pulses of the two counterpropagating fields are combined outside the cavity on a detector a beat note is observed, which represents the phase difference or difference in longitudinal mode spacing. This difference in longitudinal-mode spacing can be realized by nonreciprocal effects, such as rotation or insertion of a phase modulator pulsed at the cavity round-trip time.
