We demonstrate an all-fiber-integrated Er-doped fiber laser operating in the soliton-similariton mode-locking regime. In the similariton part of the cavity, a self-similarly evolving parabolic pulse with highly linear chirp propagates in the presence of normal dispersion. Following an in-line fiber-based birefringent filter, the pulse evolves into a soliton in the part of the cavity with anomalous dispersion. The similariton and the soliton pulses are dechirped to 75.5 and 167.2 fs, respectively, outside of the cavity. Mode-locked operation is very robust, owing to the influence of the two similariton and soliton attractors that predominate each half of the laser cavity. The experimental results are supported with numerical simulations, which provide good agreement.
我们演示了一种全光纤集成的掺铒光纤激光器，其工作在孤子-类孤子锁模状态。在腔中的类孤子部分，在正常色散的存在下，具有高度线性啁啾的自相似演化抛物线脉冲传播。在线性光纤双折射滤波器之后，脉冲在具有反常色散的腔部分演化成孤子。类孤子和孤子脉冲在腔外分别展宽到 75.5 和 167.2 fs。由于两个类孤子和孤子吸引子主导激光腔的每一半的影响，锁模操作非常稳定。实验结果得到了数值模拟的支持，两者吻合较好。
