In the present work, we report the dynamics and geometrical features of the plasma plume formed by the laser ablation of copper and graphite (carbon) targets in the presence of different transverse magnetic field. This work emphasizes on the effect of atomic mass of the plume species on the diamagnetic behaviour and geometrical aspect of the expanding plasma plume in the magnetic field. The time-resolved analysis of the simultaneously captured two directional images in orthogonal to the…

An experimental setup to study the expansion dynamics of laser blow-off plasma plume in variable transverse magnetic field.
TLDR
Generation of uniform and variable pulsed magnetic field in synchronization with pulsed plasma for the study of the expansion dynamics of laser blow-off (LBO) plasma plume and it is observed that LBO generated plume have a stronger correlation with the magnetic field compared to the conventional laser produced plasma experiments.
Confinement and dynamics of laser-produced plasma expanding across a transverse magnetic field.
TLDR
The dynamics and confinement of laser-created plumes expanding across a transverse magnetic field have been investigated and a multiple peak temporal distribution was observed for neutral species.
Plasma plume dynamics in magnetically assisted pulsed laser deposition
The expansion of a laser produced plasma perpendicular to a magnetic field is studied with a quadruple Langmuir probe and a B-dot probe. In regions where the kinetic beta is less than one, we find

TLDR
From a copper target, laser-ablated plasma was investigated by spectral- and temporal-resolved emission spectroscopy and showed significant enhancements of the spectral lines for all neutral, singly, and doubly ionized species.

Laser-plasma diamagnetism in the presence of an ambient magnetized plasma
This work is an experimental study of the diamagnetic cavity created by a dense laser-produced plasma (initially, nlpp/n0≫1) expanding into an ambient magnetized background plasma (n0=2×1012 cm−3)
Laser generated plasmas characterized under magnetic field
The confinement of laser generated plasmas by a magnetic field is exploited to analyze the properties of plasmas of different materials. The ablation threshold is approximately proportional to
Ambient gas effects on the dynamics of laser-produced tin plume expansion
Controlling the debris from a laser-generated tin plume is one of the prime issues in the development of an extreme ultraviolet lithographic light source. An ambient gas that is transparent to 13.5nm
