Available in PDF, EPUB and Kindle. Book excerpt: An experimental program is reported which investigates the basic physics underlying the surface corona preionization process in CO2 TEA lasers. Measurements were made of UV emission spectra, photoelectron density, current and voltage waveforms and laser output for a matrix of physical parameters known to influence corona preionization. Based upon experimental results, guidelines are given for the design of a corona preionized CO2 TEA laser. (Author).

Download or read book The CO2 Laser written by W.J. Witteman and published by Springer. This book was released on 2013-06-05 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The CO2-laser technology may be considered the most advanced in the laser field. Research has been stimulated strongly because of its high potential for many scientific and industrial applications. This book is primarily devoted to the main, more established developments of the CO2-laser. Advances in continuous systems, pulsed systems, mode-locked pulses, and the amplification of short pulses are dealt with in detail. This is done by giving an extensive treatment of relevant molecular physics, gas kinetics, excitation and relaxation processes, and laser physics pertinent to CO2. It also provides a thorough theoretical background of specific technologies used in various devices. Many numerical values of physical constants and accurate spectroscopic data of CO2 isotopes are included.

Available in PDF, EPUB and Kindle. Book excerpt: Lasing has been achieved at 10.6 microns using a double discharge CO2 TEA configuration. The double discharge configuration uses three electrodes. The third, 'trigger, ' electrode in this particular device consists of glass encapsulated nichrome wires. The third electrode is responsible for corona formation--the dominant preionization mechanism. A parametric analysis of the discharge was conducted. The discharge was found to be dependent on the gas mixture, the gas flow rate, the voltage rise time and the voltage pulse shape. It was found that satisfactory discharge operation leading to lasing was limited to a very small region of parameter space having a helium percentage of not less than 90% (with 5% CO2 and 5% N2), and a rise time on the order of 3 microsec. Lasing action yielded 5 joules/pulse. The energy was limited by the optical components used, and it is felt that the energy can be increased to approximately 18 joules/pulse using different circuit parameters in conjunction with improved optical components.

Book excerpt: Optical science, engineering, and technology have grown rapidly in the last decade so that today optical engineering has emerged as an important discipline in its own right. This series is devoted to discussing topics in optical engineering at a level that will be useful to those working in the field or attempting to design systems that are based on optical techniques or that have significant optical subsystems.

Download or read book Principles of Lasers written by Orazio Svelto and published by Springer Science & Business Media. This book was released on 2009-09-29 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is motivated by the very favorable reception given to the previous editions as well as by the considerable range of new developments in the laser field since the publication of the third edition in 1989. These new developments include, among others, quantum-well and muitiple-quantum-welliasers, diode-pumped solid-state lasers, new concepts for both stable and unstable resonators, femtosecond lasers, ultra-high-brightness lasers, etc. This edition thus represents a radically revised version of the preceding edition, amounting essentially to a new book in its own right. However, the basic aim has remained the same, namely to provide a broad and unified description of laser behavior at the simplest level which is compatible with a correct physical understanding. The book is therefore intended as a textbook for a senior-level or first-year graduate course and/or as a reference book. The most relevant additions or changes to this edition can be summarized as follows: 1. A much-more detailed description of Amplified Spontaneous Emission has been given (Chapter 2) and a novel simplified treatment of this phenomenon, both for homogeneous and inhomogeneous lines, has been introduced (Appendix C). 2. A major fraction of a new chapter (Chapter 3) is dedicated to the interaction of radiation with semiconductor media, either in a bulk form or in a quantum-confined structure (quantum-well, quantum-wire and quantum dot). 3.
