Ion acceleration in underdense plasmas by ultra-short laser pulses

New Journal of Physics, 2014
We report on the ion acceleration mechanisms that occur during the interaction of an intense and ultrashort laser pulse ( $I\lambda^{2}>10^{18} \text{W}\,\text{cm}^{-2}\,\mu \text{m}^{2}$ ) with an underdense helium plasma produced from an ionized gas ...

Design and development of a LIBS system on linear plasma device PSI-2 for in situ real-time diagnostics of plasma-facing materials

Nuclear Materials and Energy, 2017
Laser induced breakdown spectroscopy (LIBS) is a strong candidate for detecting and monitoring the H/D/T content on the surface of plasma facing components (PFCs) due to its capability of fast direct in situ measurement in extreme environment (e.g ...

Experimental observation of backscattered light based on different coherence between incident laser beams

High Power Laser Science and Engineering, 2013
Recent experimental results on NIF revealed a much higher stimulated Brillouin scattering (SBS) and stimulated Raman scattering (SRS) backscatter than expected; one possible reason was due to the coherence between incident laser beams.

Modelling of plasma formation during nanosecond laser ablation

Archives of Mechanics, 2011
The interaction of laser beam with a target and next with the evaporated material is studied theoretically. In the case of a nanosecond laser pulse with 1064 nm wavelength, the ablation is thermal and therefore the interaction of the laser beam with a ...

Basics of Laser-Plasma Interaction: A Selection of Topics [PDF]

, 2019
A short, tutorial introduction to some basic concepts of laser-plasma interactions at ultra-high intensities is given. The selected topics include a) elements of the relativistic dynamics of an electron in electromagnetic fields, including the ponderomotive force and classical radiation friction; b) the "relativistic" nonlinear optical transparency and

Investigation of Pre-Pulse Effects on Ultrashort-Pulse Laser Interaction with Structured Targets

Applied Sciences
The role of pre-plasma in the efficient generation of protons by intense laser-matter interaction from structured targets is investigated. Optimal energy coupling between laser and plasma is found by varying the fluence and arrival time of an ...

Laser plasma interaction physics on the LIL facility

EPJ Web of Conferences, 2013
We present an overview of the interpretation of laser plasma interaction (LPI) experiments carried out on the LIL facility. These multikilojoule experiments have been done using underdense foam targets at 0.351 μm laser light leading to high temperature ...
