| Abstract: | The problem about optimizing gain flatten of backward-pumped fiber Raman amplifier using three-wavelength pumping is transformed into the question about restricted nonlinear programming, and resolved by successive quadratic programming method. Under the direction of optimization results, experimental system is established. Utilizing amplified spontaneous emission spectrum to adjust pump powers accurately, Raman gain ripple less than 1dB in 70nm gain spectrum is attained, and the average gain is 10dB. |
