| We have studied the nonlinear propagation of time-diffracting beams in self-focusing (cubic) Kerr media. Although stable, two-dimensional localized structures (spatial solitons) are not supported by cubic media, time-diffracting beams are demonstrated to reshape spontaneously into a propagation-invariant, seemingly robust, nonlinear wave packet of finite power. Below the critical power for collapse, the spatiotemporal structure of the attracting wave packet is that of the self-focusing of the standard monochromatic beam of the same shape and power, i. e., self-focusing is swapped from the axial direction to time. Above the critical power (and with a suitable mechanism halting collapse), the spatiotemporal structure is also that of the halted collapse of the standard monochromatic beam. | |
