We have realized and studied the fiber laser based on 4-core Yb-doped fiber and multimode Bragg grating as the input reflector. The lasing efficiency slope of 55% was measured. An investigation of the output emission has shown that the far-field pattern constitutes an interference picture. That allo

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 ΞΌm has been observed. Spectral characteristics of the laser emission have been investigated.
## Abstract This study describes a wavelengthβtunable fiber laser based on a broadband fiber mirror and an etched fiber Bragg grating (FBG) with a tuning range exceeding 15 nm. The experimental results indicate that this configuration provides a simple and economical method of implementing a wavele
