Abstract
An example optical system architecture includes a diode laser source having an optical fiber. The diode laser source is configured to generate an optical signal having a main mode and side longitudinal modes and to output the optical signal along an optical path. An optical filter is in the optical path. The optical filter is configured to receive at least part of the optical signal, to output the main mode along the optical path, and to suppress the side longitudinal modes at least in part. One or more optical amplifiers are in the optical path after the optical filter. The one or more optical amplifiers are configured to receive at least part of the main mode, to amplify the at least part of main mode, and to output an amplified version of the at least part of main mode along the optical path.
