我们提出并实验证明了一个优化的双向泵浦方案，实现了小于0.7 dB的平坦度在C-和L-波段的拉曼增益和光学噪声系数，同时。为了将前向泵浦用于所提出的方法，还开发了一种具有低相对强度噪声的新型泵浦激光器。
We propose and experimentally demonstrate an optimised bidirectional pumping scheme that realizes a less than 0.7 dB flatness over C- and L-bands for both Raman gain and optical noise figure, simultaneously. In order to use forward-pumping for the proposed method, a new type of pump laser having low relative intensity noise is also developed.
