Name: Coherent light generators > Particular beam control device > Mode locking
Description: Subject matter wherein means is provided for applying to the laser resonator a time-varying perturbation at or near the frequency which corresponds to the average axial mode spacing of the laser, so as to establish a phase relationship between the oscillatory laser modes, resulting in a laser output in the form of a periodic pulse train whose repetition rate is equal to the frequency of the perturbation.
