Electron acceleration by laser plasma wedge interaction

Physical Review Research, 2023
An electron acceleration mechanism is identified that develops when a relativistically intense laser irradiates the wedge of an overdense plasma. This induces a diffracted electromagnetic wave that carries a significant longitudinal electric field and ...

Longitudinal Laser Shaping in Laser Wakefield Accelerators [PDF]

, 2000
We study the energetics of wake excitation during the laser-plasma interaction in application to laser wakefield accelerators. We find that both the wake amplitude and the accelerating efficiency (transformer ratio) can be maximized by properly shaping ...

VUV/EUV ionising radiation and atoms and ions: dual laser plasma investigations [PDF]

, 2004
The interaction of ionising radiation with atoms and ions is a key fundamental process. This report concentrates on studies of photoexcitation/photoionisation using laser-produced plasmas as continuum sources and synchronised laser plasma plumes to ...

Investigation of Plasma Formation with ns Laser by Using Focused Sub-ns Laser Probe

EPJ Web of Conferences, 2018
A laser ablation plasma formation process was investigated by shooting another laser beam. The initial plasma was created by a mildly focused nanosecond laser beam and the probe laser, which has about ten times shorter pulse length with tightly focussed ...

Impacts of Ambient and Ablation Plasmas on Short- and Ultrashort-Pulse Laser Processing of Surfaces

Micromachines, 2014
In spite of the fact that more than five decades have passed since the invention of laser, some topics of laser-matter interaction still remain incompletely studied. One of such topics is plasma impact on the overall phenomenon of the interaction and its

Note: femtosecond laser micromachining of straight and linearly tapered capillary discharge waveguides [PDF]

, 2011
Gas-filled capillary discharge waveguides are important structures in laser-plasma interaction applications, such as the laser wakefield accelerator. We present the methodology for applying femtosecond laser micromachining in the production of capillary ...
