The color of a rose, the output of a laser, and the transparency of air are but a few examples. While it may not appear that glow-in-the-dark pajamas and lasers have much in common, they are in fact different applications of similar atomic de-excitations.

Holograms are used for amusement; decoration on novelty items and magazine covers; security on credit cards and driver’s licenses (a laser and other equipment are needed to reproduce them); and for serious three-dimensional information storage. You can see that a hologram is a true three-dimensional image because objects change relative position in the image when viewed from different angles.

(credit: modification of work by Mariana Ruiz Villarreal) The process is complicated in detail, but the basics can be understood, as shown in Figure \(\PageIndex{3}\), in which a laser of the same type that exposed the film is now used to illuminate it.
