Effect of initial space distribution on the temporal form of ultrashort light pulses in the focal plane of a lens.
It is shown that by varying the space distribution of the pulse before the focusing lens it is possible to control the temporal shape of the pulse in the focal plane. The consideration is based on representation of the light pulse as a superposition of Bessel or nondiffracting beams. The analytical expression for the spatial and temporal form of a pulse in the focal plane is found.
