Abstract

A single-mode Brillouin-erbium fiber laser (BEFL) is realized using only a 5 m single-mode fiber (SMF) as Brillouin gain medium, which to our best knowledge is the shortest SMF ever used to construct a BEFL. The Brillouin pump (BP) preamplification technique is adopted using a bidirectionally amplified erbium-doped fiber amplifier inside the BEFL cavity. This BEFL presents a high optical signal-to-noise ratio (40dB), a large output power (10mW), and a low 980 nm pump threshold (15mW). Experimental results indicate that this threshold increases with the BP power. Two lower and upper BP thresholds exist for the BEFL onset and turnoff, respectively, for a fixed 980 nm pump power. Moreover, the output power of this BEFL increases linearly with the 980 nm pump power at the same slope efficiency of 10% for various BP powers, but decreases linearly with the BP power at the same slope efficiency of 26% for various 980 nm pump powers.
