Book Synopsis CO2 Laser Radiation Absorption in SF6 -air Boundary Layers by : John David Anderson (Jr.)
Download or read book CO2 Laser Radiation Absorption in SF6 -air Boundary Layers written by John David Anderson (Jr.) and published by . This book was released on 1972 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous investigators have shown that gaseous sulfur hexafluoride (SF6) is a strong absorber of radiation at 10.6 micrometers. This wavelength also corresponds to the output from common CO2 lasers. New experimental and theoretical results are presented for the 10.6 micrometers absorption coefficient and saturation properties of SF6-air mixtures at conditions near standard sea level. Variations with pressure, wavelength and temperature are measured. Results for 10 percent SF6-90 percent air at 1 atm show that such mixtures are stron absorbers of CO2 laser radiation, and that saturation intensities are larger than 10,000 watts/sq cm. Measurements of CO2 laser radiation absorption within boundary layers with SF6 injection are made on the sidewall of a small subsonic wind tunnel. The beam intensity is attenuated by several orders of magnitude due to absorption by the SF6. (Author).

Book Synopsis A Numerical Analysis of CO2 Laser Radiation Absorption in SF6 -air Laminar Boundary Layers by : John David Anderson (Jr.)
Download or read book A Numerical Analysis of CO2 Laser Radiation Absorption in SF6 -air Laminar Boundary Layers written by John David Anderson (Jr.) and published by . This book was released on 1973 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical results are presented for the radiative gasdynamic interaction associated with CO2 laser radiation absorption in SF6-air laminar compressible boundary layers. Detailed boundary layer profiles and the variation of radiative intensity are obtained for the sonic flow over a flat plate at sea level, wherein SF6 is injected into the boundary layer through the surface, and CO2 laser radiation at 10.6 micrometers is incident on the plate downstream of the injection. The numerical solution of the non-similar boundary layer equations employs a difference-differential technique. (Modified author abstract).

Book Synopsis CO2 Lasers Effects and Applications by : W Duley
Download or read book CO2 Lasers Effects and Applications written by W Duley and published by Elsevier. This book was released on 2012-12-02 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: CO2 Lasers: Effects and Applications examines and summarizes the important applications of the device in different areas of study like physics, chemistry, and engineering. In some parts of the book, the reader is assumed to be knowledgeable in university level mathematics or some specialized area in physics or chemistry. The book consists of 10 chapters where the first two establish the general concepts on lasers and CO2 lasers, respectively. Chapter 3 takes the reader further and presents a comprehensive review of optical components for use such as detectors, windows, and mirrors. Because the CO2 laser is mostly used as a heat source, the theory of laser-surface heating is relevant in the discussion. This theory is presented in Chapter 4. Chapters 5 and 6 meanwhile present a summary of observations on cutting, welding, and some related topics. The following chapters discuss the different applications of CO2 lasers in different areas and processes. Some of these applications include in the generation of thermal effect, laser deposition of thin films, spectroscopy, laser photochemistry, and meteorology and communication systems. The text is a good source of reference to both students and scientists in the areas of physics, chemistry, and engineering.
