Abstract
A laser for generating an optical comb is disclosed having an active laser medium enclosed in a resonator, a launching coupler for coupling pump light from a pump source into the active medium, an output coupler for coupling out the generated laser comb, and at least one optical filter within the resonator for generating the comb. A filter for introducing a wavelength-dependent loss within the gain profile of the active medium is inserted in the resonator. As a result, the ring gain becomes unity over a wide range, and many modes of the comb start oscillating in the resonator.
