    "abstract": "The process of optical frequency doubling can lead, in the undepleted regime,\nto the generation of a X-wave envelope with group velocity locked to the pump\nbeam. Its parameters and its angular spectrum, are directly related to the\nzero- and first-order dispersive features of the nonlinear process. This\nconstitutes a novel mechanism for spatio-temporal localization of light.",
