Abstract

A 4-meter length of erbium doped fiber (EDF), which pumped from 980nm laser diode, was used as a gain medium in the construction of a fiber laser using linear cavity configuration in different position of coupler and tunable bandpass filter (TBF). A mechanical tunable bandpass filter with 3dB bandwidth of about l.Onm and tuning resolution of O.Olnm was inserted in the cavity for tuning ability and the determination of the central wavelength of the laser output [2]. The characteristics of the output power with laser diode pump power are discussed. The output signal wavelength of the erbium doped fiber laser was broadly tuned over 35nm across the 1550nm optical C-band. The fiber laser performance and the quality of the signal generated were measured by using optical spectrum analyzer (OSA). The output characteristics of the laser were determined in term of threshold level, slope efficiency and signal-to-noise ratio.
