Though many separation processes are available for use in todays analytical laboratory, chromatographic methods are the most widely used. The applications of chromatography have grown explosively in the last four decades, owing to the development of new techniques and to the expanding need of scientists for better methods of separating complex mixtures. With its comprehensive, unified approach, this book will greatly assist the novice in need of a reference to chromatographic techniques, as well as the specialist suddenly faced with the need to switch from one technique to another.

This study provides not only an introduction to the underlying physics of laser resonators and laser beams, but also material on the application of basic principles to the design of laser resonators for most of the important types of laser in common use today. Although particular technologies have been described in specific instances, the overall aim of the text has been to emphasize design principles rather than particular implementations.
