The objective of this textbook is to give an introduction to the subject of lasers and optical engineering on a level such that undergraduate students from disciplines such as electrical engineering, physics, and optical engineering can use the book. To that end, a much basic background material central to the subject is covered in optics and laser physics. Special emphasis is put on applications, including fiber optic cables, laser machining, audio and video disc players, printing and xerography, laser associated semiconductor processing, robot vision, and medical diagnostics.
