桥接多模光纤和马米谢夫再生器有望在光纤激光器中实现脉冲能量定标。然而，多模马米雪夫振荡器的初始化仍然是一个实际的挑战。本文报道了在无主动辅助的情况下，多模Mamishev振荡器中的自启动时空模式锁定(STML)。第一次初始化锁模是不稳定的，但可以通过增加滤波器间隔来获得稳定的STML。仿真结果验证了利用马米雪夫再生器达到自启动STML的能力，并揭示了滤波器分离对自启动能力的影响。(C)2022光学出版集团
Bridging multi-mode fibers and Mamyshev regenerators holds promise for pulse energy scaling in fiber lasers. However, initialization of a multi-mode Mamyshev oscillator remains a practical challenge. Here we report self-starting spatiotemporal mode-locking (STML) in a multi-mode Mamyshev oscillator without active assistance. The first initialized mode-locking is unstable, but stable STML can be attained by increasing the filter separation. Simulations verify the capability of reaching self-starting STML using Mamyshev regenerators and unveil the effect of filter separation on the self-starting ability. (c) 2022 Optica Publishing Group
