Laser diode bụ ngwaọrụ eletrọniki nke na-eji njikọ PN yana ihe semiconductor abụọ ma ọ bụ ternary. Mgbe etinyere voltaji n'èzí, elektrọn na-agbanwe site na eriri conduction gaa na eriri valence ma wepụta ike, si otú a na-emepụta photons. Mgbe photons ndị a na-egosipụta ugboro ugboro na njikọ PN, ha ga-agbawa ìhè laser siri ike. Laser semiconductor nwere njirimara nke obere ihe na ntụkwasị obi dị elu, enwere ike ịgbanwe ugboro laser ha site na ịgbanwe ihe mejupụtara ihe, nha njikọ PN, na voltaji njikwa.
A na-ejikarị laser diode eme ihe n'ọtụtụ ebe dịka nkwukọrịta eriri optic, diski anya, igwe nbipụta laser, ihe nyocha laser, ihe ngosi laser (mpen laser), wdg. Ha bụ laser kachasị ukwuu n'ihe gbasara olu mmepụta. Na mgbakwunye, laser semiconductor nwere ọtụtụ ojiji na laser ranging, LiDAR, nkwukọrịta laser, ngwa ọgụ simulation laser, ịdọ aka ná ntị laser, nduzi na nsochi laser, mgbanye na mgbawa, njikwa akpaka, ngwa nchọpụta, wdg, na-emepụta ahịa sara mbara.
