研究目的
Investigating the performance of an erbium-doped fiber laser (EDFL) as a function of erbium-ion clustering, pumping wavelength, pumping configuration, and temperature.
研究成果
The forward pumping configuration with a 980 nm pumping wavelength is the best option for designing a widely tunable EDFL, providing the widest tuning range with a flat lasing output. Temperature variations within 30°C to 80°C have little effect on lasing performance.
研究不足
The study is based on simulation models, and practical implementation may face challenges not accounted for in the simulations. The temperature effects were only investigated within a limited range (30°C to 80°C).
1：Experimental Design and Method Selection:
The performance of an EDFL was investigated using simulation models developed via OptiSystem (version 14) for forward, backward, and bidirectional pumped erbium-doped-fiber ring laser (EDFRL) configurations.
2：Sample Selection and Data Sources:
Simulation data included pump power, pump wavelength, signal power, signal wavelength, erbium-ion concentration, and other parameters as listed in Table
3：List of Experimental Equipment and Materials:
A 20 mW laser diode was used for pumping, coupled into the EDF via an ideal WDM multiplexer. An optical isolator and a tunable filter were also used.
4：Experimental Procedures and Operational Workflow:
The lasing output power was monitored in an optical spectrum analyzer via a 90:10 output coupler, with variations in ion-clustering parameters, pumping wavelengths, pumping configurations, and temperature analyzed.
5：Data Analysis Methods:
The effects of ion-clustering, pumping wavelength, pumping configuration, and temperature on EDFL performance were analyzed through simulation results.
