Abstract

A compact single-frequency $1060\mathrm{nm}$ fiber laser based on a high-power semiconductor optical amplifier (SOA) has been proposed and demonstrated with over $40\mathrm{nm}$ wavelength tuning range. The inhomogeneous gain-broadening feature of the SOA and the unpumped ytterbium-doped fiber-based saturable absorber contribute to the single longitudinal mode lasing of the fiber laser. The maximum $3\mathrm{dBm}$ output power can be obtained with the optical signal to noise ratio larger than $50\mathrm{dB}$. Stable single-frequency operation can be maintained more than $1\mathrm{h}$ with negligible power fluctuations and low relative intensity noise.
