研究目的
To demonstrate a continuous wave (CW) wavelength-tunable Tm3+-doped fiber laser with two sampled fiber Bragg gratings (SFBGs) for applications in free space optical communication (FSOC) and fiber sensors.
研究成果
A CW wavelength-tunable Tm3+-doped fiber laser with two SFBGs at the 2 μm band was demonstrated, achieving a significant 14.44 nm wavelength range. The laser shows good stability and can be used in FSOC communication systems as a seed laser and in the fiber sensor field.
研究不足
The slope efficiency of the proposed laser is low compared to other studies, and the tuning range is limited by the tensile limitation of the bare fiber. Stress-induced loss caused by fiber fixtures in the laser cavity also affects the quality of the output laser.
1：Experimental Design and Method Selection:
The laser uses two SFBGs as the filter and reflective mirrors, with one SFBG also serving as the laser output end. The Vernier effect is utilized to achieve a wide tuning range.
2：Sample Selection and Data Sources:
The gain medium is a 2.4 m double-cladding Tm3+-doped fiber. The pump source is a multimode 793 nm laser diode.
3：4 m double-cladding Tm3+-doped fiber. The pump source is a multimode 793 nm laser diode. List of Experimental Equipment and Materials:
3. List of Experimental Equipment and Materials: Includes a (2 + 1) × 1 fiber combiner, polarization controller, SFBGs, and an optical spectrum analyzer (OSA, YOKOGAWA AQ6375).
4：5). Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The pump power is fixed at 3.67 W. The strain on SFBG1 is adjusted through a translation stage to shift the output wavelength.
5：67 W. The strain on SFBG1 is adjusted through a translation stage to shift the output wavelength. Data Analysis Methods:
5. Data Analysis Methods: The output characteristics are measured using an OSA, and the stability is tested over 50 min at intervals of 5 min.
