The electric field of an ultrashort laser pulse often fails to separate into a product of purely
temporal and purely spatial factors. These so-called spatio-temporal couplings constitute a …

Diffraction-free optical beams propagate freely without change in shape and scale.
Monochromatic beams that avoid diffractive spreading require two-dimensional transverse …

Introducing correlations between the spatial and temporal degrees of freedom of a pulsed
optical beam (or wave packet) can profoundly alter its propagation in free space. Indeed …

Diffraction places a fundamental limitation on the distance an optical beam propagates
before its size increases and spatial details blur. We show here that imposing a judicious …

Accurately characterizing the field of broadband optical pulses is required for developing
new optical sources, performing successful experiments, and interpreting experimental …

We investigate the temporal precision in the generation of ultrashort laser pulse pairs by
pulse shaping techniques. To this end, we combine a femtosecond polarization pulse …

Space-time wave packets are a class of pulsed optical beams that are diffraction-free and
dispersion-free in free space by virtue of introducing a tight correlation between the spatial …

We present a Fourier optical analysis of a typical femtosecond pulse shaping apparatus and
derive analytic expressions for the space-time dependence of the emerging waveform after …

Space-time (ST) wave packets are pulsed beams in which the spatial frequencies and
wavelengths are tightly correlated. Proper design of the functional form of these correlations …
