摘要

在超短激光腔中实现了多ghz重复频率的连续波锁模，其临界脉冲能量比传统理论预测的低100倍。作者揭示了连续往返之间的动态增益损耗和恢复是低脉冲能量从调q锁模（QSML）过渡到连续波锁模（CWML）的关键因素。除了提供对增益动态的新见解外，结果还提出了在非常高重复率下实现低阈值激光的实用途径。

Understanding low-threshold mode-locking at multi-GHz repetition rate

Continuous-wave mode-locking at multi-GHz repetition rates is achieved in an ultrashort laser cavity at critical pulse energies 100 times lower than predicted by conventional theory. The authors reveal that dynamic gain depletion and recovery between consecutive round-trips is the key factor behind a low-pulse-energy transition from Q-switched mode-locking (QSML) to continuous-wave mode-locking (CWML). As well as providing new insight into gain dynamics, the results suggest a practical route to low-threshold lasing at very high-repetition rates.
