Diode laser
Edge emitting high power diode (semiconductor) 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 single stripe diode laser mounted in a very basic C-mount package. The square copper block with a round hole is a heatsink. The actual semiconductor chip is above the hole right under the wires connecting it to the cathode terminal on top of the package. The size of the active region on the chip that produces laser radiation is typically about 1 x 100 x 500 microns. Laser radiation is emitted perpendicular to the plane of the image. Also shown is a US penny coin for scale. Photo Nov 2008.
