Abstract
A multi-wavelength laser ( ) includes an optical loop ( ) having a single optical cavity that supports a plurality of longitudinal modes, wherein the optical loop has a common gain medium ( ) to supply the necessary optical gain to provide for a plurality of lasing longitudinal modes at a plurality of lasing wavelengths. A wavelength selector ( ) is insertable into the optical loop within the optical path for selecting at least one lasing longitudinal mode ( ) from the plurality of longitudinal modes. Although not exclusively, the multi-wavelength laser ( ) is usable for WDM interferometric sensing ( ).
