Available in PDF, EPUB and Kindle. Book excerpt: Light atomic species such as oxygen atoms (O) and hydrogen atoms (H) are fundamentally important in a wide variety of combustion-related phenomena such as flame ignition, propagation, extinction and in chemical flame reactions. Furthermore, they are difficult to detect by conventional laser based optical methods (laser induced fluorescence) in combustion environments because the necessary resonance excitation wavelengths fall far into the vacuum ultraviolet (vuv) and the requisite tunable laser sources are not generally available. However, recent developments in nonlinear spectroscopic techniques such as multiphoton induced emission (MPE) and multiphoton ionization (MPI) have made direct detection of these light atoms possible. We have utilized a number of laser multiphoton excitation schemes for their detection using tunable lasers in the 190 to 400 nm range. Similar diagnostic techniques were attempted for the detection of carbon (C) and nitrogen (N) atoms in flames. The effects of laser induced photochemical pertubations on species detection in flames were also investigated. These nonlinear spectroscopic techniques have been demonstrated to be very useful in combustion studies but special care needs to be taken with respect to possible perturbations that may result from the use of short-wavelength lasers.

Available in PDF, EPUB and Kindle. Book excerpt: Laser diagnostics have been a staple for experimental combustion research as a modern tool to evaluate high temperature reacting flow environments and to contribute to the fundamental knowledge needed for improving our current combustion systems in a non-intrusive way; they also represent an essential tool for validating computational models. High pressure diagnostics are of particular importance due to the fact that the majority of practical combustion systems operate at high pressure, involving increased challenges in the measurements. The current work examines a variety of linear and non-linear light/matter interaction processes (Raman, fluorescence, and coherent anti-Stokes Raman spectroscopy or CARS) with the goal of measuring the temperature, pressure, and spatial distribution of important reacting flow species. The specific techniques involving OH planar laser induced fluorescence (PLIF), two-line OH PLIF thermometry, two-photon CO PLIF, nanosecond vibrational CARS and hybrid femtosecond/picosecond rotational CARS are all demonstrated at atmospheric pressure using a non-premixed coflow impinging jet as a study flame and examined in detail under high pressure conditions (up to 12 bar) as a coflow flame and in a calibration high pressure vessel; the implications of pressure are discussed in detail in the linear and non-linear techniques. The high pressure experimental data set shows soot laser induced incandescence (LII) as a source of interference for high pressure LIF in non-premixed flames, good agreement with 3 different chemical mechanisms, in particular at high pressure, between an OpenFOAM simulated fluorescence and the experimental pressure dependent data regarding both the spatial distribution of the OH molecule and the overall number of $OH$ molecules interacting with the excitation source. Chirp is identified as a critical parameter when using a second harmonic bandwidth compressor in the hybrid fs/ps CARS configuration, and the chirped CARS signal depends strongly on probe delay in N2 experiments. High quality high pressure data can be achieved once chirp influence has been quantified accurately. Together the combination of diagnostics studied provide insights into high pressure laser diagnostics challenges beyond what is currently available.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the Proceedings of a two-week NATO A.S.I. on "Analytical Laser Spectroscopy", held from September 23 to October 3, 1982 in Erice, Italy. This is the 9th annual course of Inter national School of Quantum Electronics organized under the auspices of the "E. Majorana" Center for Scientific Culture. The Advanced Study Institute has been devoted to the analytical applications of lasers in spectroscopy. Atomic and molecular spec troscopy is one of the research fields in which the use of lasers has had a dramatic impact. New spectral information, difficult or impos sible to gather by classical spectroscopy, extremely high resolution spectroscopy of atoms and molecules made possible by the overcoming of the Doppler effect, selective excitation and detection of single atomic and molecular quantum states are just few typical examples of how laser sources have revolutionized the field, offering challenging problems of both fundamental and applied nature. Among the possible approaches to a course on Analytical Laser Spectroscopy, the one which emphasizes the scientific and technologi cal aspects of the advanced laser techniques when applied to chemical analysis has been chosen. In fact, it reflects the new policy of the School to stress the advanced scientific and technological achieve ments in the field of Quantum Electronics. Accordingly, the course has given the broadest information on the ultimate performances of analytical laser spectroscopy techniques and the perspectives of their applications.

Available in PDF, EPUB and Kindle. Book excerpt: Progress in Analytical Atomic Spectroscopy, Volume 2 discusses several concerns regarding analytical atomic spectroscopy. The book contains five parts that tackle a specific area of concern. The first part covers the basic principles and applications of atomic fluorescence spectrometry and contains eight chapters that tackle several areas, such as optical pumping process, analytical detectability, plasma diagnostic, and Doppler-free high resolution spectroscopy. The second part discusses trace element analysis of food and beverages by atomic spectrometry. The third part covers the determination of trace metals in ultrapure water; this part contains three chapters that discuss the sources and control of contamination; techniques and methodology; and evaluation of the reliability of existing data. The following part tackles the interference in flame spectrometry, and the last part discusses emission spectroscopic analysis using cool flames. The book will be of great interest to researcher whose work involves analytical atomic spectroscopy.
