"a useful book which will be of value to specialist researchers in the field. Its clarity of presentation makes it accessible to a wider audience." --Journal of Modern Optics
"Letokhov and his colleagues have given an excellent account of the infrared multiple photon method of studying highly vibrationally excited states." --Optical Quantum Electronics
"Readers will find this book provides a broad overview of the techniques and applications of laser spectroscopy for sensing. The well-written background, containing basic theory of laser spectroscopy sensing, provides the reader with the essentials for understating the remainder of the book. The inclusion of many spectroscopic techniques gives the reader a broad understanding of various spectroscopic methods available and describes each method's advantages and limitations. This is very useful knowledge for the researcher who needs to use optical sensing methods in their work. Laser scientists and engineers as well as those using laser sensing methods for environmental, medical, military, and material processing applications will also find this book very informative based on the technical details and broad number of laser spectroscopy methods covered." --IEEE Electrical Insulation Magazine, November/December 2014
