Paper Abstract

An efficient and tunable Er3+/Yb3+ co-doped cladding pumped fiber ring laser operating in L-band is demonstrated. Rejecting the amplified spontaneous emission (ASE) of C-band by a fiber Bragg grating (FBG) into the same Er3+/Yb3+ co-doped fiber, the laser can operate in L-band stably. The insertion of the FBG can reduce the lasing threshold, and narrow the 3dB line-width of output laser. Using a two-section high-birefringence fiber loop mirror as a wavelength filter, the output wavelength can be tuned over 40nm range. The lasing threshold is about 48.80mW and the side mode suppression ratio is better than 51dB.
