Abstract
A method and apparatus are described including a laser with a plurality of internal or external actuators for affecting an optical frequency of light output by the laser, wherein the plurality of actuators have a corresponding plurality of different frequency response bands for changing optical properties of the laser and a corresponding plurality of actuation ranges of optical frequencies affected. Also included is an optical detector, and a plurality of optical paths configured to direct light output by the laser onto the detector. A laser controller is configured to provide a plurality of inputs to the plurality of actuators based on a detector signal output from the optical detector and the corresponding frequency response bands and actuation ranges.
