Diode Laser Spectroscopy for Manufacturing Process and Environmental Monitoring
Spectroscopic and Kinetic Studies Using Ultra-Sensitive Absorption and Room Temperature Diode Lasers

Languages : en
Pages : 145
Book Description
A program to apply diode lasers and ultra-sensitive absorption techniques to a variety of important Air Force problems is described. In this program, new gas phase sensors were developed for several applications including: diagnostics for advanced chemical oxygen iodine lasers (COIL), gas phase sensors for atmospheric studies and environmental monitoring, process manufacturing, and development of control strategies based on outputs from the sensors. In this report we present experimental measurements of collisional broadening coefficients of selected transitions in molecular oxygen and water vapor. We make comparisons to earlier measurements and to models for line broadening. We also discuss the production of optical amplification in molecular iodine pumped by a low power visible wavelength diode laser. Finally we present data from characterizations of diode lasers appropriate for development into sensitive diagnostics for the NCi/I laser system.

Tunable Diode Laser Spectroscopy, Lidar, and DIAL Techniques for Environmental and Industrial Measurements
Monitoring of Gaseous Pollutants by Tunable Diode Lasers
Author: R. Grisar
Publisher: Springer
ISBN: 9789400939929
Category : Science
Languages : en
Pages : 184
Book Description
By now it has been nearly twenty years since the pioneering studies at the MIT-Lincoln Laboratories, Lexington, USA, demonstrated the unique capabilities of lead salt tunable diode lasers (TDL) for infrared absorption spectroscopy. The progress in the use of TDL instrumentation for a wide variety of scientific applications was described by a great number of papers since, however, comparatively few meetings were specifically devoted to this subject. In 1980 the conference on "High Resolution Infrared Spectroscopy Applications and Developments" at the National Bureau of Standards in Gaithersburg, USA, reviewed the state of the art of tunable diode lasers together with Fourier Transform Spectroscopy and other laser spectroscopic techniques. Three years later in 1983 the SPIE Conference in San Diego, USA, dedicated one meeting to "Tunable Diode Laser Development and Spectroscopy" Applications. It appeared appropriate after a further interval of three years to organize another meeting about this quickly advancing field. In November of 1986 an International Symposium on "Monitoring of Gaseous Pollutants by Tunable Diode Lasers" was organized by and held at the Fraunhofer-Insti tut fuer Physikalische Messtechnik in Freiburg, FRG. The main emphasis of this conference was put on the applications of TDL techniques to the solution of problems of environmental relevance : The measurement of atmospheric trace gases and the monitoring of exhaust gases from automobile and power plant stack emitters. The state of diode laser development and application of TDL instruments to scientific molecular spectroscopy were not directly subjects of the meeting.

Handbook of Spectroscopy
Author: G¿nter Gauglitz
Publisher: John Wiley & Sons
ISBN: 3527321500
Category : Science
Languages : en
Pages : 2011
Book Description
This second, thoroughly revised, updated and enlarged edition provides a straightforward introduction to spectroscopy, showing what it can do and how it does it, together with a clear, integrated and objective account of the wealth of information that may be derived from spectra. It also features new chapters on spectroscopy in nano-dimensions, nano-optics, and polymer analysis. Clearly structured into sixteen sections, it covers everything from spectroscopy in nanodimensions to medicinal applications, spanning a wide range of the electromagnetic spectrum and the physical processes involved, from nuclear phenomena to molecular rotation processes. In addition, data tables provide a comparison of different methods in a standardized form, allowing readers to save valuable time in the decision process by avoiding wrong turns, and also help in selecting the instrumentation and performing the experiments. These four volumes are a must-have companion for daily use in every lab.
