Optics and Lasers is an introduction to engineering and applied optics, including not only elementary ray and wave optics, but also lasers, holography, coherence, fibers, and optical waveguides. It stresses physical principles, applications, and instrumentation. The textbook will be most useful to the practicing engineer or experimental scientist, graduate student, or advanced undergraduate. It contains more than enough material from which to select the core of an introductory optics course and sufficient to form the bulk of a more advanced course.
