Methods for producing mode locking in a laser may be classified as either "active" or "passive". Active methods typically involve using an external signal to induce a modulation of the intracavity light. Passive methods do not use an external signal, but rely on placing some element into the laser cavity which causes self-modulation of the light. The most common active mode-locking technique places a standing wave electro-optic modulator into … WebThe theory of mode-locking is covered in a number of readily available general references, thus the following explanation is primarily heuristic, concentrating on qualitative results.
