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 ...

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 ...
