This remarkable Handbook covers the broad field of laser science and technology. It does so with clarity so that it can be useful to individuals with a wide variety of backgrounds, and with care and completeness so that those interested in specialized applications of lasers should also find it useful. It is a large handbook, more than 130 chapters and 170 expert authors-too large for a briefcase, but so complete and useful that it may be a necessity for any scientific or technical library.
