摘要
提出了一种基于脉冲自身强度相关调制的新型全保偏主动锁模激光器。利用脉冲强度前馈结构结合双驱动强度调制器，实现与脉冲自身强度相关的幅度调制，形成两种完全不同的稳定锁模状态。理论研究了脉冲前馈在主动锁模中的作用，实验验证了脉冲前馈在10 GHz谐波锁模时抑制了超模噪声，在基频锁模时可饱吸收。该激光器工作稳定，具有多种输出脉冲特性。
Abstract
A novel all-polarization-maintained actively mode-locked laser with pulse self-intensity-dependent modulation is proposed. The pulse feed-forward structure and the dual-drive modulator are combined to realize the self-intensity-dependent modulation and two completely different stable mode-locking regimes. The function of the pulse feed-forward is studied theoretically. The experimental results demonstrate that the pulse feed-forward path suppresses supermode noise in the 10 GHz mode locking and makes absorption saturate in the fundamental mode-locking regime. Thanks to the multiple output property and stable operation, many applications will benefit from the novel laser.
