Generating intense ultrashort pulses with high-quality spatial modes iscrucial for ultrafast and strong-field science. This can be accomplished bycontrolling propagation of femtosecond pulses under the influence of Kerrnonlinearity and achieving stable propagation with high intensity. In thiswork, we propose that the generation of spatial solitons in periodic layeredKerr media can provide an optimum condition for supercontinuum generation andpulse compression using multiple thin plates. With both the experimental andtheoretical investigations, we successfully identify these solitary modes andreveal a universal relationship between the beam size and the criticalnonlinear phase. Space-time coupling is shown to strongly influence thespectral, spatial and temporal profiles of femtosecond pulses. Taking advantageof the unique characters of these solitary modes, we demonstrate single-stagesupercontinuum generation and compression of femtosecond pulses from initially170 fs down to 22 fs with an efficiency ~90%. We also provide evidence ofefficient mode self-cleaning which suggests rich spatial-temporalself-organization processes of laser beams in a nonlinear resonator.
