Abstract
Aspects of the present disclosure are directed to laser interferometric systems, methods, and structures exhibiting superior laser phase noise tolerance particularly in seismic detection applications wherein laser requirements are advantageously relaxed by employing a novel configuration wherein the same laser which generates an outgoing signal is coherently detected using the same laser as local oscillator and fiber turnarounds are employed that result in the cancellation and/or mitigation of undesired mechanical vibration.
