Longitudinal Laser Shaping in Laser Wakefield Accelerators [PDF]

open access: yes, 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 ...

High-Efficiency Copper Removal by Nitrogen Plasma-Assisted Picosecond Laser Processing

open access: yesMicromachines, 2022
Copper (Cu) removal efficiency is a key parameter in the processing of Cu-based electronic devices. Herein, a nitrogen plasma-assisted picosecond (ps) laser process for Cu removal is presented.

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

open access: yes, 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 ...

Electron acceleration by laser plasma wedge interaction

open access: yesPhysical 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 ...

Properties of plasmonic arrays produced by pulsed-laser nanostructuring of thin Au films

open access: yesBeilstein Journal of Nanotechnology, 2014
A brief description of research advances in the area of short-pulse-laser nanostructuring of thin Au films is followed by examples of experimental data and a discussion of our results on the characterization of structural and optical properties of gold ...

Novel scintillator-based x-ray spectrometer for use on high repetition laser plasma interaction experiments.

open access: yesReview of Scientific Instruments, 2018
The characterisation of x-rays from laser-plasma interactions is of utmost importance as they can be useful for both monitoring electron dynamics and also applications in an industrial capacity.

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

open access: yesEPJ 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

open access: yesMicromachines, 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

Physics of laser plasma interaction and particle transport in the context of inertial confinement fusion

open access: yesNuclear Fusion, 2018
Lasers are unique tools for transporting extremely high powers over large distances, but transfer of such a power from photons to matter in small volumes is a very complicated problem.

Investigation of the wakefield generation in the interaction of the intense laser pulse with gas [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2021
In the present work, the formation of the wakefield during the interaction of intense laser pulse with a gas medium has been investigated by using PIC simulation code, including the ionization process.
