The authors report a highly-efficient, short, robustly single-frequency and linearly polarised Er3+:Yb3+ codoped fibre laser with fibre-grating Bragg reflectors. An output power of 19mW for 100mW of 980nm diode pump power and a slope efficiency relative to a launched pump power of 55% is demonstrated. The RIN of the laser was < -157 dB/Hz and the laser linewidth was 300 kHz.
