From Understanding Lasers


The internal workings of semiconductor diode lasers are more complex than those of gas or solid-state lasers because they depend on the unique properties of semiconductors. This chapter starts by explaining the basics of semiconductor physics, then explains how semiconductor diodes can produce light, and how that light emission can be used to create a laser. Then it describes the diverse types of semiconductor diode lasers that are now in wide use in applications from playing CDs to powering high-power solid-state and fiber lasers.
