Timing-injection locking in a self-starting Mamyshev oscillator induced by the dissipative Faraday instability

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Changqing Li, Ran Xia, Yutai Zhao, Yifang Li, Jia Liu | Summary: Mamyshev oscillators (MOs), a novel class of passively mode-locked fiber lasers, serve as an excellent platform to explore complex nonlinear dynamics, ranging from localized sturctures to chaos. Despite their versatility, achieving self-starting mode-locking remains a […]
