Lasers are essential to an incredibly large number of applications. Today, they are used in bar code readers, compact discs, medicine, communications, sensors, materials processing, computer printers, data processing, 3D-imaging, spectroscopy, navigation, non-destructive testing, chemical processing, color copiers, laser “shows”, and in the military. There is hardly a field untouched by the laser. But what exactly is so unique about lasers that makes them so effective?
