This introductory text is the only one available that elucidates the physics and engineering principles relevant to all lasers. As lasers gain prominence in our high-tech world, many technicians and engineers who work with them often lack formal training in electro-optics, leading to inefficient use of these vital tools. The Fourth Edition provides a comprehensive understanding of laser functionality and limitations, guiding readers on selecting the appropriate laser for various applications and how to enhance laser performance. With a blend of clarity and technical depth, it covers the characteristics and applications of commercial lasers globally, alongside discussions on light, optics, fundamental laser elements, and modification techniques. The updated edition features new chapter-end problems and expanded content on topics such as material and wavelength, diode laser arrays, quantum-cascade lasers, fiber lasers, thin-disk and slab lasers, ultrafast fiber lasers, Raman lasers, quasi-phase matching, and optically pumped semiconductor lasers. This resource is ideal for students, technicians, engineers, and professionals seeking a thorough introduction to laser technology.

Young adult introduction to optics and light, including what light is and does, simple optics and how they work, the eye, light sources, light detection and robot vision, infrared and ultraviolet light, Optical instruments, cameras and television, fiber optics, light and life, ray guns and reality.
