Book Gas Ratio and Pressure Effects on the 6328 A0 Transition of the Helium neon Gas Laser

Download or read book Gas Ratio and Pressure Effects on the 6328 A0 Transition of the Helium neon Gas Laser written by Edwin Karl Freytag and published by . This book was released on 1967 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a review paper of current literature in the area of pressure effects on gaseous lasers. This thesis discusses the mechanisms which relate the relative power output of the 6328 A[superscript 0] neon transition to total and partial pressure variations of the helium-neon gaseous laser. The operation of the helium-neon gas system utilized to obtain this visible transition is described. The rates and modes of production and destruction of the helium metastable atoms are presented. The interaction of the two gases and the requirements for sustained population inversion of the neon laser levels are considered, including inelastic electron collisions and radiation trapping. Some assumptions and approximations are made to prevent the analysis from becoming too cumbersome. The effective transition rates of the upper and lower laser levels are shown to be functions of the total and partial pressures. Some available data is presented. It is shown that good agreement exists between the data and the proposed models. Some inconsistencies between the data of various authors exist so that these models do not give a quantitative analysis of the lasing process but rather represent segments of the lasing process.

Book Handbook of Lasers

Download or read book Handbook of Lasers written by Marvin J. Weber and published by CRC Press. This book was released on 2019-04-30 with total page 1224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lasers continue to be an amazingly robust field of activity. Anyone seeking a photon source is now confronted with an enormous number of possible lasers and laser wavelengths to choose from, but no single, comprehensive source to help them make that choice. The Handbook of Lasers provides an authoritative compilation of lasers, their properties, and original references in a readily accessible form. Organized by lasing media-solids, liquids, and gases-each section is subdivided into distinct laser types. Each type carries a brief description, followed by tables listing the lasing element or medium, host, lasing transition and wavelength, operating properties, primary literature citations, and, for broadband lasers, reported tuning ranges. The importance and value of the Handbook of Lasers cannot be overstated. Serving as both an archive and as an indicator of emerging trends, it reflects the state of knowledge and development in the field, provides a rapid means of obtaining reference data, and offers a pathway to the literature. It contains data useful for comparison with predictions and for developing models of processes, and may reveal fundamental inconsistencies or conflicts in the data.

Book Compilation of Atomic and Molecular Data Revelant to Gas Lasers

Download or read book Compilation of Atomic and Molecular Data Revelant to Gas Lasers written by E. W. McDaniel and published by . This book was released on 1980 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume serves to update most of the areas covered in the previous documents. Such areas include all nuclear processes, and atomic collisions occurring at high energies, i.e., above about 100 eV impact energy. However, even in those areas where new data are not presented here, references are given to past volumes in order to facilitate access to the previous data. Another function of the present volume is to expand somewhat the scope of our data coverage, both with respect to atomic nd molecular structural properties and with respect to atomic collisions (by the latter term, we mean two- and three- body collisions between electrons, ions, atoms, molecules, and photons at impact energies sufficiently low that nuclear forces are unimportant). New species and sets of collision partners that have recently assumed importance are treated here, and other systems that may become important in the gas laser context are given attention. A significant amount of new material is also added to the chapter on surface impact phenomena, partly because of current interest in hollow-cathode lasers.

Book Compilation of Atomic and Molecular Data Relevant to Gas Lasers Volume VII

Download or read book Compilation of Atomic and Molecular Data Relevant to Gas Lasers Volume VII written by and published by . This book was released on 1980 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume and the succeeding volume are the seventh and the eighth in a series that presents data relevant to research and development in the field of gas lasers. The present volumes serve to update most of the areas covered in the previous documents. Those areas not treated here are considered to have been adequately dealt with earlier, as far as immediate data needs are concerned. However, even in those areas where new data are not presented here, references are given to past volumes in order to facilitate access to the previous data. Another function of the present work is to expand somewhat the scope of our data coverage, both with respect to atomic and molecular structural properties and with respect to atomic collisions.

Book Progress in Atomic Spectroscopy

Download or read book Progress in Atomic Spectroscopy written by W. Hanle and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 811 pages. Available in PDF, EPUB and Kindle. Book excerpt: W. HANLE and H. KLEINPOPPEN In 1919, in the first edition of Atombau and Spektrallinien, Sommerfeld referred to the immense amount of information which had been accumu lated during the first period of 60 years of spectroscopic practice. Sommer feld emphasized that the names of Planck and Bohr would be connected forever with the efforts that had been made to understand the physics and the theory of spectral lines. Another period of almost 60 years has elapsed since the first edition of Sommerfeld's famous monograph. As the editors of this monograph, Progress in Atomic Spectroscopy, we feel that the present period is best characterized by the large variety of new spec troscopic methods that have been invented in the last decades. Spectroscopy has always been involved in the field of research on atomic structure and the interaction of light and atoms. The development of new spectroscopic methods (i.e., new as compared to the traditional optical methods) has led to many outstanding achievements, which, together with the increase of activity over the last decades, appear as a kind of renaissance of atomic spectroscopy.
