This book was released on 2018-11 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The final phase of modeling solar pumped lasers considers the photodissociation of the perfloralkyl molecules n - C3F7I, t - C4F9I, and i - C3F7I. Computer modeling was compared to laboratory data and good agreement between theory and experiment was achieved. The following is a summary of the modeling of solar pumped lasers. A perfloride gas enters a tube at a point z = 0 and travels a distance L at a velocity, W, and then exits at the point z = L. During the flow, the gas is solar pumped over the initial distance 0 less than or = z less than or = z sub 0, where z sub 0 is less than or equal to L. The perfloride gas interacts chemically with light and a chain of chemical reactions occur. Heinbockel, John H. Unspecified Center NAG1-757...

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this research is to quantify laser pulse energy and intensity on P-branch and rotational lasing transitions and provide data from well-defined experiments for interpretation and analysis of computational studies of HF and DF chemical lasers. A compendium of technical reports and publications on rotational non-equilibrium effects in the HF and DF lasers is presented. Modeling efforts have assessed the sensitivity of laser performance to various kinetic mechanisms. The importance of rotational non-equilibrium is identified and the possible effect of vibrational to rotational energy transfer on P-branch and rotational lasing is considered.

Available in PDF, EPUB and Kindle. Book excerpt: A computer modeling study of pulsed H2+F2 and D2+F2 chemical lasers has been conducted. This work was directed toward understanding the role of kinetic rotational relaxation and vibrational-rotational relaxation mechanisms in HF and DF lasers. This study resulted in very comprehensive computer models that could predict spectral characteristics of pulsed laser performance using kinetics rate equation data and experimental conditions. In addition, experiments were conducted on a flash initiated pulsed H2+F2 laser facility to generate data to compare with the models developed in this study. Models were also developed that demonstrated the performance of pulsed laser driven amplifiers and optical resonance transfer lasers. Finally, simple models were constructed that permit efficient prediction of pulse energy and pulse power. (Author).

Book excerpt: Lasers with a gaseous active medium offer high flexibility, wide tunability, and advantages in cost, beam quality, and power scalability. Gas lasers have tended to become overshadowed by the recent popularity and proliferation of semiconductor lasers. As a result of this shift in focus, details on modern developments in gas lasers are difficult to find. In addition, different types of gas lasers have unique properties that are not well-described in other references. Collecting expert contributions from authorities dealing with specific types of lasers, Gas Lasers examines the fundamentals, current research, and applications of this important class of laser. It is important to understand all types of lasers, from solid-state to gaseous, before making a decision for any application. This book fills in the gaps by discussing the definition and properties of gaseous media along with its fluid dynamics, electric excitation circuits, and optical resonators. From this foundation, the discussion launches into the basic physics, characteristics, applications, and current research efforts for specific types of gas lasers: CO lasers, CO2 lasers, HF/DF lasers, excimer lasers, iodine lasers, and metal vapor lasers. The final chapter discusses miscellaneous lasers not covered in the previous chapters. Collecting hard-to-find material into a single, convenient source, Gas Lasers offers an encyclopedic survey that helps you approach new applications with a more complete inventory of laser options.

Book excerpt: Applied Atomic Collision Physics, Volume 3: Gas Lasers describes the applications of atomic collision physics in the development of many types of gas lasers. Topics covered range from negative ion formation in gas lasers to high-pressure ion kinetics and relaxation of molecules exchanging vibrational energy.

Comprised of 14 chapters, this volume begins with a historical summary of gas laser developments and an overview of the basic operating principles of major gas laser types. The discussion then turns to the mechanism of formation of negative ions in gas lasers; ion-ion recombination in high-pressure plasmas; electron-ion recombination in gas lasers; and collision processes in chemical lasers. Subsequent chapters focus on high-energy carbon dioxide laser amplifiers; spectroscopy and excited state chemistry of excimer lasers; rare-gas halide lasers; transient optical absorption in the ultraviolet; and pre-ionized self-sustained laser discharges. The final chapter considers the stability of excimer laser discharges. This book will be of interest to physicists and chemists.
