Abstract :
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 19 mW for 100 mW of 980 nm 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
