Paper Abstract

The authors report a medium-power widely tunable single wavelength fiber laser. The laser wavelength was tuned from 1530 nm to 1575 nm. The gain medium consisted of a double-clad erbium-ytterbium codoped fiber. An un-pumped elliptical core erbium-doped fiber was used as a saturable absorber inside the cavity to reduce the laser linewidth and mode hopping. The output power of the laser at each lasing wavelength was more than 100 mW. The linewidth of the laser was 8 MHz, measured using a scanning Fabry-Perot spectrum analyzer of resolution 6.5 MHz. The laser was stable at room temperature with an intensity fluctuation of less than 0.2 dB.
