摘要

A single-longitudinal mode selection is realized in a linear-cavity tunable fiber laser constructed using a Faraday rotator mirror and a partial reflectance fiber Bragg grating as the cavity ends. At both tuning wave-lengths of 1543.47 and 1557.52 nm, the measured optical signal-to-noise ratio is larger than 40 dB and a line-width less than 1 MHz is obtained. It is based on the usage of a piece of gain fiber type saturable absorber as the mode filter. The pumping power efficiency is improved by 10 by recycling the residual pump power to the gain medium.
