Abstract :
This paper describes the design and operation of a narrow linewidth, linear cavity, erbium-doped fiber laser with saturable absorber. The saturable absorber, spliced to a narrowband fiber Bragg grating, acts as a transition fiber grating with narrow bandwidth that automatically tracks the lasing wavelength. Laser output power was ~2.5mw at 1544.39nm for a pump power of 55mw, the signal to noise ratio (SNR) was approximately 57dB, and the slope efficiency was approximately 5%.
