✦ Synopsis

On the base of the phase shifted fiber Bragg grating of 4 cm length written in the active non-PM Yb-doped fiber, a resonator with distributed feedback (DFB) has been formed. The single frequency single polarization unidirectional generation with the output power up to 4.5 mW has been obtained. The spectral and energy performances of the single frequency DFB fiber laser depending on the pump laser parameters and ways of pump wave coupling have been investigated. The competition between orthogonal polarization states has been also studied, and the single polarization regime of 0.5 mW power has been achieved.

Yb-doped cladding-pumped fiber laser with linearly-polarized output emission was realized. To obtain linear-polarization operation we have applied Bragg grating written in the fiber with high birefringence as the input reflector. The polarization extinction ratio was of 17 dB.
