We have realized a set of multimode lasers based on a double-clad Yb-doped fiber and Bragg gratings written on a graded-index multimode fiber. Efficient laser operation in the spectral range of 1.03-1.09 μm has been observed. Spectral characteristics of the laser emission have been investigated.

✦ Synopsis
We report wide wavelength tuning in a double-clad ytterbium-doped fiber laser. The laser cavity consists of an array of broadband high-reflection fiber Bragg gratings and a bulk grating as output coupler and wavelength selection element. The proposed fiber laser configuration combines low intra-cavity loss of fiber Bragg grating mirrors with wide wavelength tuning of bulk gratings. We demonstrate > 70 nm wavelength tuning range, limited only by the available fiber Bragg gratings.
