✦ Synopsis

We have made and studied a set of the fiber lasers based on Ho-doped fiber with high concentration of the active ions. For the first time the spectral efficiency in a range of 2.02 -2.15 μm was determined. The highest output power of 4.2 W was detected at 2.1 μm with the efficiency slope of 34%. This value of the efficiency is highest for pure holmium-doped silica fibers.

## Abstract An actively mode‐locked fiber laser (AMLFL) based on the hybrid gain of a dispersion‐shifted fiber (as the Raman gain medium) and an Erbium‐doped fiber (EDF) is introduced. The fiber Raman gain mechanism can effectively suppress the gain competition of an EDF, which usually results into

## Abstract A novel interrogation of fiber Bragg grating (FBG) in a strain sensor, which is based on Er‐doped fiber laser's transient regime, is reported. The applied strain on FBG changes the laser cavity loss, which in turn modifies the laser's transient regime. The strain value can be obtained b

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
