This book was released on 1970 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical solutions are given for vibrational population inversions created in CO2-N2-He mixtures due to shock wave heating of a cold gas. The results indicate that population inversions between the (040) and (001) energy levels of CO2 and, to a lesser degree, between the (200) and (001) levels, can be created in the vibrational nonequilibrium flow behind a normal shock front. The properties of these inversions as a possible laser medium are assessed; the results indicate that the laser properties of this shock-induced nonequilibrium flow are not as promising as those of lasers operating on the principle of rapid expansions.

This book was released on 1970 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are given for equilibrium properties behind incident and reflected normal shock waves in CO2-N2-He mixtures wherein the gas may be vibrationally excited but not chemically reacting. A rapid numerical iterative analysis is described, and the results are given in simple graphical form for convenient use in shock tube and shock tunnel experiments. The results are anticipated to be of particular use in determining reservoir conditions for shock tunnel experiments dealing with vibrational population inversions in rapidly expanding mixtures.

Download or read book Gasdynamic Lasers An Introduction written by John D. Jr. Anderson and published by Elsevier. This book was released on 2012-12-02 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gasdynamic Lasers: An Introduction is a 12-chapter introductory text to major development generations of gasdynamic lasers, focusing on their underlying physical and fundamental aspects. The opening chapters discuss the basic detailed physical phenomena that ultimately are responsible for producing gasdynamic laser action and the methods of calculating the performance of these devices. These topics are followed by a chapter on confirmation of the performance calculations through arc and shock tunnel experiments. The discussion then shifts to vibrational relaxation process behind normal shock waves in CO2-N2-He mixtures and assesses their population inversions occurring in the nonequilibrium flow. Other chapters explore the concepts of downstream mixing and optical cavity in gasdynamic lasers, as well as the laser beam extracted from these devices. A systematic study of aerodynamic windows that use supersonic flow across the aperture is presented in the concluding chapters, along with the phenomena associated with gasdynamic laser diffusers. This introductory text will be of great value to professional scientists and engineers, as well as to students and workers in the field who are interested in interdisciplinary applied science.

Download or read book Gasdynamic Laser written by S. A. Losev and published by Springer. This book was released on 1981-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with gasdynamic lasers (GDL)-high-energy sources of co directional radiation. The theory and practice of gasdynamic lasers herent are based on three fields of modern science: quantum electronics, physico chemical kinetics, and gasdynamics. This circumstance has determined the content of this book, which can be divided into two parts. The first four which occupy a considerable part of the book, prepare the reader chapters, for discussing the theoretical and experimental results of up-to-date GDL studies. The necessity of such a presentation is dictated by the fact that gasdynamic lasers can be a subject of interest for readers who are experts one of the mentioned fields, or those who have just begun studying in only GDLs. Such a representation is based on the experience gained by the author over several years in delivering lectures on this subject to students of Moscow State University. These lectures fonned the basis of the book, which can also be used as a text. The basic information on gasdynamic lasers is contained in the last two chapters of the book. These chapters give mathematical models of processes occurring in existing high-energy infrared GDLs (C0 GDLs, carbon monoxide 2 GDLs, etc. ), experimental results for these lasers, and also consider some possible new designs of GDLs. Of greatest interest in this respect are the attempts to create recombination electronic GDLs and plasmadynamic lasers.
