摘要：

The dynamical response of a laser simultaneously subject to frequency-shifted optical feedback and pump modulation is investigated both theoretically and experimentally. We show that the amount of light reinjected in the intra-cavity laser can be determined by the pump modulation contrast, either for a destructive interference condition between the optical feedback and the pump modulation, or near the parametric instability threshold.
