What is a diode.
Laser diodes are electrically pumped semiconductor lasers in which the gain is generated by an electric current flowing through a p–n junction or (more frequently) a p–i–n structure. In such a heterostructure of a bipolar interband laser, electrons and holes can recombine, releasing the energy portions as photons.
