Book Description
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.

Book Description
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.
