Publisher Summary Silica fibers can change their optical properties permanently when they are exposed to intense radiation from a laser operating in the blue or ultraviolet spectra region. Fiber gratings can be designed to operate over a wide range of wavelengths extending from the ultraviolet to the infrared region.

Publisher Summary The chapter discusses diffraction gratings. This novel method of engine control and the development of high-fidelity replication processes made a variety of high-quality gratings commercially available in the 1950s. In these developments, every effort had been directed to rule perfectly equispaced parallel grooves.
