The nonlinear polarization evolution-based passively mode-locked fiber laser is attracting increasing attention that can be attributed to its variety of operating regimes. However, the precise polarization tuning required to achieve these different regimes and the extreme vulnerability of these lasers to environmental disturbances have substantially hindered their widespread applications. Here, we experimentally demonstrate the first genetic algorithm-based real-time automatic mode-locked fiber laser, in which the fitness functions for the different regimes are based on temporal information only and where a modified genetic algorithm is proposed to accelerate the mode-locking time. The laser demonstrates an outstanding time-consumption performance, particularly when searching the second-order harmonic mode-locking regime and the Q-switching regime.

基于遗传算法的快速实时自动锁模光纤激光器

基于非线性偏振演化的被动锁模光纤激光器正引起越来越多的关注，这可归因于其多种工作机制。然而，实现这些不同状态所需的精确偏振调谐以及这些激光器对环境干扰的极端脆弱性大大阻碍了它们的广泛应用。在这里，我们通过实验证明了第一个基于遗传算法的实时自动锁模光纤激光器，其中不同状态的适应度函数仅基于时间信息，并且提出了一种改进的遗传算法来加速锁模时间。该激光器表现出出色的时间消耗性能，特别是在搜索二阶谐波锁模机制和 Q 开关机制时。
