Abstract:
1. A laser source for emitting a set of output beams, with at least some of the output beams in the set having a different center wavelength, the laser source comprising: a gain medium having a first facet, the gain medium being adapted to generate a beam that exits the first facet; a feedback device positioned in the path of the beam, the feedback device redirecting at least a portion of the beam back to the gain medium; a device mover that continuously adjusts an angle of incidence of the beam on the feedback device; a control system that selectively directs pulses of power to the gain medium as the device mover is continuously adjusting the angle of incidence; and a position detector that generates a position signal that relates to the angle of incidence of the beam on the feedback device; and wherein the control system selectively directs pulses of power to the gain medium based on the position signal from the position detector.
