Beam delivery is the means by which the laser beam propagates from the generator to the target of interest. Since light is part of the electromagnetic spectrum, the manner in which the beam propagates is determined by the characteristics of the electromagnetic spectrum. This chapter provides a brief introduction to the electromagnetic spectrum. The electromagnetic spectrum, of which visible light is part, exhibits both wave‐like and particle‐like properties. Birefringence is the phenomenon whereby a light beam that is incident on a material is refracted into two rays, the ordinary ray and the extraordinary ray. The chapter explores a simplified one‐dimensional propagation of the electric vector of an electromagnetic plane wave. Beam expanders are normally used for changing the size of the output beam. Beam splitters are optical elements that are used to divide an incoming beam into two, and through cascading, into any number of parts.
