Semiconductor, (diode), lasers have a wide variety of applications including optical storage, telecommunications, medical, and others. Diode lasers have a dominant market share among all lasers produced. They account for 56% of laser market revenue, (2006 data). Edge-emitting high power diode lasers produce up to several Watts of optical power. Pictured here is a conceptual image of a diode laser, (High Heat Loading, HHL, package), radiating a beam of light.
