Space-time wave packets (STWPs) constitute a broad class of pulsed optical fields that are
rigidly transported in linear media without diffraction or dispersion, and are therefore …

The temporal characterization of ultrafast laser pulses has become a cornerstone capability
of ultrafast optics laboratories and is routine both for optimizing laser pulse duration and …

Laser wakefield accelerators (LWFAs) produce extremely high gradients enabling compact
accelerators and radiation sources but face design limitations, such as dephasing, occurring …

Controlling the group velocity of an ultrashort laser pulse by means of spatio-temporal
couplings has been proposed to overcome the inherent limitations in laser–plasma …

We propose a computationally efficient method to derive the unitary evolution that a
quantum state is most sensitive to. This allows one to determine the optimal use of an …

“Flying focus” techniques produce laser pulses with dynamic focal points that travel
distances much greater than a Rayleigh length. The implementation of these techniques in …

Although a plethora of techniques are now available for controlling the group velocity of an
optical wave packet, there are very few options for creating accelerating or decelerating …

Vacuum birefringence produces a differential phase between orthogonally polarized
components of a weak electromagnetic probe in the presence of a strong electromagnetic …

The combination of temporal chirp with a simple chromatic aberration known as longitudinal
chromatism leads to extensive control over the velocity of laser intensity in the focal region of …

A laser pulse composed of a fundamental and properly phased second harmonic exhibits an
asymmetric electric field that can drive a time-dependent current of photoionized electrons …
