Linear Mode-locked DFB-fiber Laser with Repetition Rate Control
An embodiment of the invention relates to a multi-segment all-fiber laser device (10). The device includes a first active fiber laser segment (20), a first grating (25), a second grating (35), and a gain-phase coupling fiber segment (40) arranged between the first and second gratings, said gain-phase coupling segment providing coupling of gain and phase between said first and second gratings. The second grating may be provided in a second active fiber laser segment (30) and the phase may be adjusted by a control pump source (70).
