摘要
从描述双折射光纤环形激光器动力学模型出发,模拟并分析了脉冲序列在非线性偏振旋转锁模光纤激光器环形腔内的演化过程,得出光纤快慢轴与起偏器之间的角度、以及双折射强度是影响锁模脉冲序列均匀性的重要因素,通过将普通单模光纤绕制成环产生应力双折射的方法进行了验证,并获得了中心波长1566.8 nm,脉宽为1.5 ps的稳定短脉冲序列.
Abstract
By using a model of a mode-lock fiber laser with a nonlinear polarizer, numerical simulation of pulse propagation in birefringent fiber was carried out. As a conclusion, the alignment angle of the polarizer with fast axis is proposed the important elements that influence the uniformity of the pulse. Experimentally, 1.5 ps mode-locked pulse series centered at 1556.8 nm were obtained.
