Under APC operation, the optical power emitted from the laser is held constant by adjusting the drive current into the device. Because semiconductor lasers can have lifetimes in the range of decades, monitoring the slow increase of laser current overtime as the laser degrades is the preferred way to measure laser lifetime.

Solid objects that are large enough to see and handle are rarely composed of a single crystal, but instead are made of a large number of single crystals, known as crystallites, whose size can vary from a few nanometers to several meters.
