Laser shaping and optimization of the laser-plasma interaction [PDF]

AIP Conference Proceedings, 2001
The physics of energy transfer between the laser and the plasma in laser wakefield accelerators is studied. We find that wake excitation by arbitrary laser shapes can be parameterized using the total pulse energy and pulse depletion length. A technique for determining laser profiles that produce the required plasma excitation is developed. We show that

Off-harmonic optical probing of high intensity laser plasma expansion dynamics in solid density hydrogen jets

Scientific Reports, 2022
Due to the non-linear nature of relativistic laser induced plasma processes, the development of laser-plasma accelerators requires precise numerical modeling.

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 ...
