Numerical simulations of the spatial-temporal dynamics and mode-locking in a waveguide array laser cavity

摘要

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.
