We report on a master-oscillator ytterbium-doped fiber amplifier system with up to 133 W of continuous-wave output power using a tunable narrow-linewidth external-cavity diode laser seed source. Stable tunable high-power operation was demonstrated from 1040 nm to 1085 nm with more than 12 dB suppression of amplified spontaneous emission.
