Ultrasensitive Laser Spectroscopy covers the experimental methods involved in various sensitive techniques to which lasers have been applied for the study of weak transitions. This book is organized into seven chapters. Each chapter discusses the theories, experiments, and application of the specific technique. A discussion on the advantages, disadvantages, and modifications made in each technique is also provided. Ultrasensitive techniques considered in this text include photoacoustic, one- and two-photon excitation, absorption, mass, and laser ionization spectroscopies. Other chapters examine the techniques of laser intracavity-enhanced, laser absorption, and emission spectroscopy. This book will be of value to spectroscopists, analytical chemists, and researchers in the field of ultrasensitive analysis.

Keeping abreast of the latest techniques and applications, this new edition of the standard reference and graduate text on laser spectroscopy has been completely revised and expanded. While the general concept is unchanged, the new edition features a broad array of new material, e.g., ultrafast lasers (atto- and femto-second lasers), coherent matter waves, Doppler-free Fourier spectroscopy, interference spectroscopy, quantum optics and gravitational waves and still more applications in chemical analysis, medical diagnostics, and engineering.

"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 information Comprehensive review of cavity-enhanced methods *Written by the researchers who pioneered these spectroscopies *Discusses cavity-enhanced optical instrumentation Reviews scientific discoveries unearthed using these methods

Laser Spectroscopy IX documents the proceedings of the Ninth International Conference on Laser Spectroscopy, held in Bretton Woods, New Hampshire, June 18-23, 1989. The scientific program consisted of oral and poster presentations. There were 52 invited talks organized into 14 topical sessions, some with panel discussions. About 60 additional invited contributions were presented in three evening poster sessions. Also included were 15 post deadline oral and poster presentations. These proceedings contain summaries of essentially all of these contributions. The contributions made by researchers at the conference are organized into 14 parts. Part I focuses on laser cooling. Part II presents studies on laser spectroscopy. Part III includes papers on cavity Q.E.D. Parts IV, V, and VI examine noise and coherence, quantum size effects, and surface spectroscopy, respectively. Part VII deals with laser light sources. Part VIII includes papers on trapped ion spectroscopy. Part IX covers ultrafast spectroscopy while Part X takes up fundamental measurements, including those of positronium, the Rydberg constant, and lead and thallium isotopes. Parts XI-XIV cover, respectively, molecular spectroscopy and dynamics, applications in radiation forces, highly excited states and dynamics, and laser spectroscopy for biomedicine.

Intracavity Laser Absorption Spectroscopy (ICLAS) at IR wavelengths offers an opportunity for spectral sensing of low vapor pressure compounds. We report here an ICLAS system design based on a quantum cascade laser (QCL) at THz (69.9 [micrometers]) and IR wavelengths (9.38 and 8.1 [micrometers]) with an open external cavity. The sensitivity of such a system is potentially very high due to extraordinarily long effective optical paths that can be achieved in an active cavity. Sensitivity estimation by numerical solution of the laser rate equations for the THz QCL ICLAS system is determined. Experimental development of the external cavity QCL is demonstrated for the two IR wavelengths, as supported by appearance of fine mode structure in the laser spectrum. The 8.1 [micrometers] wavelength exhibits a dramatic change in the output spectrum caused by the weak intracavity absorption of acetone. Numerical solution of the laser rate equations yields a sensitivity estimation of acetone partial pressure of 165 mTorr corresponding to ~ 200 ppm. The system is also found sensitive to the humidity in the laboratory air with an absorption coefficient of just 3 x 10−7 cm−1 indicating a sensitivity of 111 ppm. Reported also is the design of a compact integrated data acquisition and control system. Potential applications include military and commercial sensing for threat compounds such as explosives, chemical gases, biological aerosols, drugs, banned or invasive organisms, bio-medical breath analysis, and terrestrial or planetary atmospheric science.
