title: Wavelength tunability and pulse duration control in frequency shifted feedback Er-doped fiber lasers.
abstract: This paper presents the experimental studies on the all-fiber frequency shifted feedback erbium laser. Impact of the gain section profile on laser operation is shown. Two methods of wavelength tuning are presented. We obtained 8.3 and 10 nm tuning range in electrical and manual tuning respectively. Pulse duration can be also controlled and changed from 2 to 5 ps. The shortest pulses duration we have obtained was 1.7 ps.
