Programmable Focal Elongation and Shaping of High-Intensity Laser Pulses using Adaptive Optics
P. Blum, A. Puchert, E. Archer +7
Controlling the intensity distribution of laser pulses in the focal region is essential for optimizing optically generated plasma waveguides and enabling advanced plasma accelerati…

High brightness, symmetric electron bunch generation in a plasma wakefield accelerator via a radially-polarized plasma photocathode
James Chappell, Emily Archer, Roman Walczak +1
The plasma photocathode has previously been proposed as a source of ultra-high-brightness electron bunches within plasma accelerators. Here, the scheme is extended by using a radia…

On the localization of the high-intensity region of simultaneous space-time foci
Emily Archer, Bangshan Sun, Roman Walczak +2
Simultaneous space-time focusing (SSTF) is sometimes claimed to reduce the longitudinal extent of the high-intensity region near the focus, in contradiction to the original work on…
