Multiple foci are created along the propagation direction of a laser beam using simultaneous spatial and
temporal focusing of an ultrafast laser pulse in conjunction with parametric pulse shaping. The pulses
are characterized with scanning SEA TADPOLE. The longitudinal and transverse positions of the foci
are controlled using phase and amplitude shaping in a 4-f laser pulse shaping system. Measurements of
the pulse duration as a function of spatial position of the foci are in agreement with the predictions of a
Fourier optics model.
