摘要

In 1958, the first laser (light amplification through the stimulated emission of radiation) was created in Bell Labs by two brilliant men: Arthur L. Schawlow, a researcher, and a consultant named Charles H. Townes. This first laser was a simple, but effective array: a small ruby rod surrounded by a coiled flash tube (much like that of a camera). Since then, lasers have been used for so many applications that it is impossible to keep track of them all. There is even a mirror placed on the moon by Apollo 11 that bounces a laser beam back to earth for distance measuring. While many of these applications are interesting, this article will concentrate on diode lasers and their applications to compact discs, digital video discs, and other data storage media.
