研究目的
Investigating the impact of third-order dispersion on the characteristics of random distributed feedback fiber lasers.
研究成果
The inclusion of TOD in the NLSEs leads to asymmetrical power evolution in the fiber laser. The spectral power density becomes narrower with increased input power, and fluctuations are observed in the spectrum when TOD is considered.
研究不足
The study focuses on the impact of TOD and does not explore higher-order dispersion effects beyond the third order. The practical implementation and experimental validation of the simulations are not discussed.
1：Experimental Design and Method Selection:
The study uses the nonlinear Schr€odinger equations (NLSEs) to simulate the laser characteristics, including the power evolution of pump, forward, and backward Stokes waves.
2：Sample Selection and Data Sources:
The simulation parameters are based on theoretical models and previous works in the field.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned, but involves optical fiber and laser setup.
4：Experimental Procedures and Operational Workflow:
Numerical simulation of NLSEs with and without TOD to study power evolution and spectral power density.
5：Data Analysis Methods:
Comparison of output characteristics with and without TOD, and analysis of the impact of fiber nonlinear coefficient and input power.
