摘要
通过实验和数值模拟研究了全正色散被动锁模光纤激光器中增益支配孤子的产生。实验观测和数值模拟结果分别证实了由腔导致的峰值功率钳位效应的存在。激光器性能对腔的结构的依赖性得到研究。研究结果表明:在光纤激光器中,能否获得具有更高脉冲能量的增益支配孤子是由腔的结构例如腔内非线性管理和输出比率选取决定的。
A thorough experimental and numerical investigation of the generation of gain﹣guided soliton in passively mode﹣locked fiber lasers made of purely positive dispersion fibers was presented. The cavity﹣induced peak power clamping effect was verified experimentally and numerically. The dependence of the performance of the laser on the cavity structure was explored. The results show that the gain﹣guided soliton with much higher pulse energy obtained in the fiber laser is determined by the cavity structure and relate this to the cavity nonlinear management and output ratio choice.
