Abstract: Provided is a fiber ring laser capable of obtaining a back up laser light and standard light having a wavelength continuously tuned in a single mode with equal spacing of 12.5GHz, 25GHz, 50GHz or 100GHz recommended by ITU-T Recommendation G. 692 & G. 694.1 in a C-band and an L-band using a fiber tunable etalon filter, an air gap etalon filter and a saturable absorber in an optical fiber laser resonator having a serial ring shape using a C-band optical amplifier and an L-band optical amplifier. The fiber ring laser can generate laser light having a wavelength tuned by more than 70nm, excellent output power flatness and a source spontaneous emission ratio of more than 7OdB in 361 channels with equal spacing of 25GHz by applying a bias voltage to a voltage-operated piezoelectric element of a tunable etalon filter. A single longitudinal mode operation of the fiber ring laser can be obtained by using a saturable absorber serving as a narrow-bandwidth filter.
