Cavitation and charge separation in laser-produced copper and carbon plasma in transverse magnetic field
Narayan Behera, Ajai Kumar, R. K. Singh
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 dif…
A 3D Magnetohydrodynamic simulation for the propagation of plasma plume transverse to applied magnetic field
Bhavesh G. Patel, Narayan Behera, R. K. Singh +2
We have carried out a 3D ideal-MHD (Magnetohydrodynamic) simulation to study the evolution of laser generated plasma plume in a moderate external magnetic field (0.13 T) oriented p…
Study of diamagnetism in laser-produced plasma using B-dot probe
Narayan Behera, R. K. Singh, G. Veda Prakash +3
Time-varying diamagnetism in laser-produced plasma moving across the transverse magnetic field with different field strengths has been studied using fast imaging and magnetic probe…
Characterization of atmospheric pressure plasma plume
G. Veda Prakash, Kiran Patel, Narayan Behera +1
In order to optimize the parameters of the plasma plume for atmospheric pressure plasma applications such as biological and industrial applications, it is highly necessary to thoro…
Observation of ion acceleration in nanosecond laser generated plasma on a nickel thin film under forward ablation geometry
Jinto Thomas, Hem Chandra Joshi, Ajai kumar +1
In this article we report acceleration observed for ions in a forward ablation geometry of 50 nm thick nickel film coated on a glass plate under nanosecond laser ablation. A detail…
Controlling the size distribution of nanoparticles through the use of physical boundaries during laser ablation in liquids
Kaushik Choudhury, Rajesh K. Singh, Prasoon Kumar +3
A simple, yet effective method of controlling the size and size distributions of nanoparticles produced as a result of laser ablation of target material is presented. The method em…
