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 …

Reaching high energies with a plasma-wakefield accelerator may require use of multiple
stages. This coupling of beams from one stage to another can be nontrivial due to a …

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

This article first gives the authors' perspectives on how the field of plasma-based
acceleration (PBA) developed and how the current experiments, theory, and simulations are …

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 …

“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 …

Chirped laser pulses are investigated theoretically for laser wakefield (LW) and direct laser
(DL) acceleration of electrons in the plasma-bubble regime. Chirping of laser pulse with a …

In nonlinear Thomson scattering, a relativistic electron reradiates the photons of a laser
pulse, converting optical light to x rays or beyond. While this extreme frequency conversion …

Emittance is a beam quality that is vital for many future applications of advanced
accelerators, such as compact free-electron lasers and linear colliders. In this paper, we …

Electrostatic waves play a critical role in nearly every branch of plasma physics from fusion
to advanced accelerators, to astro, solar, and ionospheric physics. The properties of planar …
