LD10–Optical Feedback Regimes Suitable for Distance Measurement with a Ring Laser
We numerically study the behavior of a ring laser subject to bidirectional delayed optical feedback, when the isolated laser is in the quasi-unidirectional regime. We find different regimes, two of which are of special interest, because the laser switching period, between the clockwise and the counter-clockwise mode, is linearly related to the time of flight […]
