Laser diodes form a subset of the larger classification of semiconductor p–n junction diodes. Forward electrical bias across the laser diode causes the two species of charge carrier – holes and electrons – to be “injected” from opposite sides of the p–n junction into the depletion region. Holes are injected from the p-doped into the n-doped, and electrons vice versa, semiconductor The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively en.wikipedia.org
