    Abstract

    An ultra-short ring-cavity Brillouin-erbium fiber laser (BEFL), whose cavity length is only 10 m, is demonstrated. The BEFL adopts a section of normal erbium-doped fiber (EDF) with a length of 4 m as the gain medium. Nonlinear Brillouin gain and linear erbium-doped fiber amplifier (EDFA) gain are both introduced into the EDF by using the Brillouin pump and the 980 nm pump outside the cavity, respectively. Experimental results demonstrate that the BEFL operats at single-longitudinal mode with a high signal-to-noise ratio (>40 dB), a low pump threshold (~20 mW), and a high output power (>10 mW). Moreover, the Brillouin pump not only decides the output wavelength of the BEFL, but also greatly affects its pump threshold and output power.
