Abstract

We present a cladding-pumped single-frequency, single-mode erbium:ytterbium codoped fiber master-oscillator power amplifier source generating up to $151\mathrm{W}$ of continuous-wave output power at $1563\mathrm{nm}$ with 33% slope efficiency and $20\mathrm{dB}$ gain. This source was also tunable and had a stable operation range of $1546\text{to}1566\mathrm{nm}$ at an output power level in excess of $125\mathrm{W}$. The doped fiber exploited a large-core design for improved power handling and mitigation of stimulated Brillouin scattering. There was no sign of having stimulated Brillouin scattering even at the highest power. Despite a large core $(V=12)$, the output beam was nearly diffraction limited $(M^2=1.1)$. The source showed slight rollover at over $100\mathrm{W}$ of output power because of the onset of emission from ytterbium, centered at $1060\mathrm{nm}$.
