Book Description
A high resolution infrared cavity ringdown laser absorption spectrometer has been developed to study proposed HEDM molecules and metal containing clusters. Using a novel tunable pulsed Alexandrite ring laser, we are able to generate tunable visible radiation with ca, 40 MHz bandwidth. This tunable visible light is downconverted to the infrared using stimulated Raman scattering in H2 and D2. With this system, tunable radiation from the UV to the far infrared can be generated with ca, 100 MHz bandwidth. We will test this system using our pulsed supersonic laser vaporization source to study both metal and carbon containing species. Infrared Cavity Ringdown Spectroscopy has also been used to study water clusters in both pulsed supersonic beams and pulsed discharged nozzles.

Book Description
Efforts focused on four activities related to the central objective of studying metal-containing clusters, HEDM molecules, and clusters of ceramic materials. Nineteen AFOSR supported papers were published on the following topics (including five journal cover articles) : 1) Development of high resolution (100 MHz), high sensitivity pulsed infrared cavity ringdown spectroscopy as a general tool for trace species characterization. 2) Infrared cavity ringdown system with medium (900 MHz) resolution constructed and operational. 3) IR studies of hydrogen bonding in water, methanol, ethanol, and butanol clusters carried out. 4) More difficult IR experiments on laser vaporized carbon and silicon carbide initiated.

Book Description
"Cavity-Enhanced Spectroscopy" discusses the use of optical resonators and lasers to make sensitive spectroscopic measurements. This volume is written by the researcchers who pioneered these methods. The book reviews both the theory and practice behind these spectroscopic tools and discusses the scientific discoveries uncovered by these techniques. It begins with a chapter on the use of optical resonators for frequency stabilization of lasers, which is followed by in-depth chapters discussing cavity ring-down spectroscopy, frequency-modulated, cavity-enhanced spectroscopy, intracavity spectroscopies, microresonators and cavity-enhanced comb filters. This book is aimed towards a reader with a background in optics and spectroscopy, but who is unfamiliar with the methods discussed in the book. *Practical implementation informationComprehensive review of cavity-enhanced methods*Written by the researchers who pioneered these spectroscopies*Discusses cavity-enhanced optical instrumentationReviews scientific discoveries unearthed using these methods

Book Description
The objectives of this effort were as follows: (1) extend the technical development of pulsed infrared (IR) cavity ringdown spectroscopy to longer wavelengths and higher spectral resolution; (2) develop its capacity as a general tool for trace gas analysis; and (3) study spectra, structures, hydrogen tunneling dynamics of hydrocarbon ions and complexes of relevance to ion-enhanced combustion processes. High-resolution, pulsed infrared cavity ringdown laser spectroscopy was developed and implemented for the study of carbon clusters and hydrocarbon ions. Several supersonic molecular beam sources of ions and hydrocarbons were constructed and tested by infrared cavity ringdown spectroscopy. The Stokes downconversion of pulsed visible laser radiation into the mid-infrared was explored in solid and liquid hydrogen media in an effort to explore more powerful and convenient infrared sources. Cavity ringdown studies of several different carbon/hydrocarbon systems were carried out. Nine related publications and three conference presentations are listed.

Book Description
In the new edition the editors have preserved the basic concept and structure, with the involvement of some new authors - all recognized experts in laser spectroscopy. Each chapter addresses a different technique, providing a review and analysis of the current status, and reporting some of the latest achievements. With the key formulas and methods detailed in many sections, this text represents a practicable handbook of its subject. It will be a valuable tool both for specialists to keep abreast of developments and for newcomers to the field needing an accessible introduction to specific methods of laser spectroscopy - and also as a resource for primary references.
