Book Description
The editors have assembled a world-class group of contributors who address the questions the combustion diagnostic community faces. They are chemists who identify the species to be measured and the interfering substances that may be present; physicists, who push the limits of laser spectroscopy and laser devices and who conceive suitable measuremen

Book Description
Tighter regulations of harmful substances such as NOx, CO, heavy metals, particles, emissions from commercial plants and automobiles reflect a growing demand for lowering the anthropogenic burdens on the environment. It is equally important to monitor controlling factors to improve the operation of industrial machinery and plants. Among the many me

Book Description
The editors have assembled a world-class group of contributors who address the questions the combustion diagnostic community faces. They are chemists who identify the species to be measured and the interfering substances that may be present; physicists, who push the limits of laser spectroscopy and laser devices and who conceive suitable measurement schemes; and engineers, who know combustion systems and processes. This book assists in providing guidance for the planning of combustion experiments, in judging research strategies and in conceiving new ideas for combustion research. It provides a snapshot of the available diagnostic methods and thier typical applications from the perspective of leading experts in the field.

Book Description
This work details tunable laser applications of broad interest, historical significance and potential future value. Atomic and molecular spectroscopy, interferometry, lightening triggering, imaging, laser radar, lidar and gyroscopes are discussed. The work focuses on various sources of coherent radiation such as optical parametric oscillators, external cavity semiconductors lasers, and dye, gas, C02, ultrashort-pulse and free-electron lasers.

Book Description
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 190-400 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 perturbations on species detection in flames were also investigated. Keywords: Atoms, Laser induced fluorescence, Multiphoton ionization, Optogalvanic, Flames, Fuel, Oxidizer, Laser, Dye laser.

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.
