Spectroscopic Measurements of Magnetic Field and Electron Density on Wire Array and Laser Plasmas
… field and electron density distributions within plasmas are crucial parameters in the study of high energy density laboratory plasmas. These measurements are challenging because often the magnetic fields undergo significant spatial and temporal fluctuations. Of the few measurement techniques …

Field emission of ZnO nano-structures produced by laser ablation
… designed to investigate the properties of laser produced plasmas, with in-situ time of flight mass spectrometry, for deposition of ZnO materials for applications as field electron emission sources. The results from the work are concerned with the study of the important physical processes …

Laser, optical and electrical diagnostics of colliding laser-produced plasmas
… and explore potential applications of colliding laser produced plasmas. When two plasmas collide there are two extreme scenarios that can play out – the plumes can either interpenetrate or stagnate depending on the ion-ion mean free path. During interpenetration, the plasmas stream through each …

Interactions of intense optical and extreme-ultraviolet lasers with atoms and solids
… of intense optical and extreme-ultraviolet laser pulses with atoms and solids. The work was divided into two main parts: The first part describes studies on laser-produced plasmas done at the National Centre for Plasma Science and Technology in Dublin City University using an intense optical …

Analysis of a laser induced plasma in high pressure SF6 gas for high-voltage, high-current switching
<p>The Laser Triggered Switch Program at Sandia National Laboratories is an intensive development study to understand and optimize the laser triggered gas switch (LTGS) for the Z-Refurbishment (ZR) project. The laser triggered gas switch is the final command-triggered switch in the machine, and …

One and two photon absorption of atoms and ions
… with special emphasis on photoabsorption in a laser-produced strontium plasma. The dual laser plasma (DLP) technique has been employed to carry out these studies and adapted to include an optical parametric oscillator (OPO), tuneable in the visible wavelength range (410-700 nm), to permit …

Debris Characterization And Mitigation Of Droplet Laser Plasma Sources For Euv Lithography
… plasma produced by either a gas discharge or a laser. This study concentrate only on the laser produced plasma source because of its advantages of scalability to higher repetition rates. The design of a the laser plasma EUVL light source consists of a plasma produced from a high-intensity …

A one dimensional hydrodynamic simulation of colliding quasi neutral plasma systems
Studies of colliding laser-produced plasmas are of interest in several fields of research, including fusion energy generation, pulsed-laser deposition and potentially as intense short wavelength (X-ray and EUV) light sources. Computer simulations of such systems are a valuable tool in reconciling …
