Mode-locked X-wave lasers.
We theoretically demonstrate X-waves as global attractors that enable mode-locking of a laser cavity operating in the normal dispersion regime. This result is based upon a fully comprehensive physical model of the laser cavity, where the nonlinear discrete diffraction dynamics of a waveguide array mediates the spontaneous periodic generation of spatio-temporal X-waves.
