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 …

We demonstrate an experimentally simple and high-spectral-resolution version of spectral
interferometry (SEA TADPOLE) that can measure complicated pulses (in time) at video rates …

Young's boundary wave theory provides an alternative view of diffraction being an
interference of a geometric wave and a boundary wave. Here, we show theoretically and …

Using a recently developed technique (SEA TADPOLE) for easily measuring the complete
spatiotemporal electric field of light pulses with micrometer spatial and femtosecond …

Experimental investigations on Young's boundary diffraction wave are presented where a
wavefront division interferometric scheme is used on diffracted wavefront to generate two …

We study the diffraction of Gaussian pulses and beams within the framework of boundary
diffraction wave theory. For the first time the boundary diffraction wave theory is applied to …

An alternative interpretation of the diffraction of blazed transmission gratings with moderate
structure period is proposed according to a modified extended scalar theory (MEST). The …

An alternative interpretation of the phenomenon of edge diffraction is proposed according to
a new separation of the Fresnel function. The subfields are investigated in the problem of …

We analyze the spatio-temporal intensity of sub-20 femtosecond pulses with a carrier
wavelength of 810 nm along the optical axis of low numerical aperture achromatic and …

Propagation of diffracted beams in free space has already been identified. One possible
solution is derived from the Helmholtz wave equation and this solution is named as …
