A highly efficient tuneable Brillouin fiber laser (BFL) amplified by Er 3+/Yb 3+ co-doped double-clad fiber amplifier (EYDFA) is demonstrated. In this work, a ring BFL and a double-pass EYDFA are used as a seed oscillator and power amplifier, respectively. With 10 km long non-zero dispersion shifted fiber (NZ-DSF), the seed BFL has the maximum output power of - 5 dBm, side mode suppression ratio of 30dB and stimulated Brillouin scattering (SBS) threshold of 5 dBm. The amplified BFL output has the maximum output power of 400 mW and a side mode suppression ratio of more than 50 dB. The EYDFA provides a flat gain in the wavelength region of 1545 nm to 1566 nm.
