ABSTRACT:
A laser is fabricated from an optical transmission medium having a laser cavity with an rare earth (e.g. Erbium) doped portion. At least one longitudinal mode is suppressed using a plurality of series coupled Fabry-Perot cavities an optical grating, or a combination thereof. Ring lasers and linear structures are disclosed.
