Search for: [Abstrakt = "In this paper, we propose a multiwavelength erbium\-doped fiber laser \(MW\-EDFL\). The configuration of the MW\-EDFL consists of several linear Fabry–Perot \(FP\) cavities and a master\-oscillation\-power\-amplifier \(MOPA\). These linear FP cavities are partially overlapped and include several sections of EDFs, fiber Bragg gratings \(FBGs\), and a fiber loop mirror \(FLM\). In our design, a low cost broadband FLM and six narrowband FBGs were used to obtain a stable six\-wavelength fiber laser at room temperature. Using a section of EDF as an MOPA near the output end, the output power of the MW\-EDFL is promoted. The characteristics of the MW\-EDFL were also simulated by the OptiAmplifier software tool. The results of simulations and experiments match each other very well. The optimizing EDF length of the MOPA is about 1.5 m and the MOPA gains are about 4 dB to 7.5 dB. The linewidth, wavelength drift, and power fluctuation of the MW\-EDFL are about 450 kHz, 0.05 nm, and 0.4 dB, respectively."]
