摘要
In recent years, multi-wavelength lasers have attracted much attention due to their wide applications in various fields. In this Letter, we experimentally demonstrate a high-power multi-wavelength Yb-doped fiber laser with the aid of an acoustic-optic tunable filter, in which the wavelength interval, the intensity of each channel, and the number of lasing channels can be tuned independently. As a result, the operating wavelength tuning range covers 1040.0 to 1090.0 nm and the maximal output power reaches 15.7 W, which is higher than the previous reports by more than three orders of magnitude. The wavelength interval can be adjusted from 2.6 to 50 nm and the spectral profile can be arbitrarily controlled. Furthermore, the number of wavelength channels can be adjusted from 1 to 4. This work will provide a reference for achieving high-power spectral-flexible fiber sources.
