Book Synopsis The Interaction of Suspended Atmospheric Particles with Laser Radiation by : J. R. Triplett
Download or read book The Interaction of Suspended Atmospheric Particles with Laser Radiation written by J. R. Triplett and published by . This book was released on 1972 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: SUSPENDED PARTICLES. Initial breakdown in either the vaporized particle or in the shock-heated adjacent gas may result in a laser-supported detonation or in a subsonic ionization wave. The nonlinear, nonequilibrium kinetic equations describing the energy distribution of free electrons, the vibrational excitation of molecules, the dominant electronic excitation, attachment, and ionization reactions and their inverses, electron heating by the laser, and electron diffusion, are solved numerically. The dominant eigenvalue of the Jacobian of these equations is investigated as a criterion for breakdown. Calculations for vaporized silica and air at temperatures from 300K to 6000K under irradiation by a CO2 laser show expected lowering of breakdown threshold for preheated material. Heating of particle vapor and subsequent formation of a shock wave are calculated with a Lagrangian gasdynamic method. Preliminary theoretical predictions for the effects of particles on lowering of the air breakdown threshold are then obtained. (Abstract Modified Abstract).
Book Synopsis Effects of Particulate Matter on Atmospheric Propagation of CO2 Laser Radiation by : David C. Smith
Download or read book Effects of Particulate Matter on Atmospheric Propagation of CO2 Laser Radiation written by David C. Smith and published by . This book was released on 1973 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two main nonlinear propagation problems encountered by high power CO2 laser radiation in the atmosphere are gas breakdown and thermal blooming. The influence of particulate matter on gas breakdown and also on thermal blooming was investigated. Typical atmospheric conditions contain approximately 1000 particles/cc. The presence of these particles in the air path of a high power laser beam can dramatically influence the propagation of the beam. This is illustrated by a photograph which shows particles being vaporized and ionized by a high power pulsed CO2 laser beam. The plasma balls generated not only attenuate the laser radiation, but they also act as scattering centers with completely different scattering characteristics than the original particles. The hot vapor can also act as a thermal source which could cause self-induced thermal distortion of subsequent laser pulses.

Book Synopsis Laser Induced Breakdown Spectroscopy on Suspended Particulate Matter in an Electrodynamic Balance by : Richard A. Warren Jr.
Download or read book Laser Induced Breakdown Spectroscopy on Suspended Particulate Matter in an Electrodynamic Balance written by Richard A. Warren Jr. and published by . This book was released on 2013 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research focuses on the two problems listed above: sample control issues and sources of signal variation, which limit analyte quantification. The electrodynamic balance, which has been used by previous researchers for optical characterization of aerosols7 is used here for LIBS measurements. This technique provides complete control of confined, charged aerosol particles. With this precise handling capability, consistent laser-particle and plasma-particle interactions are observed with both spectrally integrated / time resolved and time integrated / spectrally resolved detectors to provide details on the processes involved for micrometer sized charged aerosol particles.
Book Synopsis Laser-Driven Sources of High Energy Particles and Radiation by : Leonida Antonio Gizzi
Download or read book Laser-Driven Sources of High Energy Particles and Radiation written by Leonida Antonio Gizzi and published by Springer Nature. This book was released on 2019-09-05 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a selection of articles based on inspiring lectures held at the “Capri” Advanced Summer School, an original event conceived and promoted by Leonida Antonio Gizzi and Ralph Assmann that focuses on novel schemes for plasma-based particle acceleration and radiation sources, and which brings together researchers from the conventional accelerator community and from the high-intensity laser-matter interaction research fields. Training in these fields is highly relevant for ultra-intense lasers and applications, which have enjoyed dramatic growth following the development of major European infrastructures like the Extreme Light Infrastructure (ELI) and the EuPRAXIA project. The articles preserve the tutorial character of the lectures and reflect the latest advances in their respective fields. The volume is mainly intended for PhD students and young researchers getting started in this area, but also for scientists from other fields who are interested in the latest developments. The content will also appeal to radiobiologists and medical physicists, as it includes contributions on potential applications of laser-based particle accelerators.
