Mechanisms of spatiotemporal mode-locking [PDF]
Nature Physics, 2020 Mode-locking is a process in which different modes of an optical resonator establish, through nonlinear interactions, stable synchronization. This self-organization underlies light sources that enable many modern scientific applications, such as ultrafast and high-field optics and frequency combs.
