Unidirectionally Pumped Raman Fiber Laser

In this dissertation, the author presents the academic and experimental researches on a unidirectionally pumped Raman fiber Laser profile.From coupling equation, the dynamic process of the Laser oscillating has been simulated by setting the Stock's frequency shift Raman Laser mode coupling equation.Based on the model above, the fiber length, the reflectivity of the output fiber grating and the pumping power has been optimized.The author constructs a unidirectionally pumped Raman fiber Laser system. The experimental study is focus on the Laser actions related with the gain fiber length and the reflectivity of output coupling. The academic result matches the Laser well.
