Diode laser bụ ngwaọrụ eletrọnịkị nke na-eji njikọ PN nwere ihe ọnụọgụ abụọ ma ọ bụ ternary semiconductor. Mgbe a na-etinye voltaji n'èzí, electrons na-agbanwe site na band conduction gaa na valence band ma hapụ ike, si otú ahụ na-emepụta foton. Mgbe foton ndị a na-atụgharị ugboro ugboro na nkwụsị PN, ha ga-agbawapụ ọkụ laser siri ike. Laser semiconductor nwere njirimara nke miniaturization na ntụkwasị obi dị elu, enwere ike gbanwee ugboro ole laser ha site n'ịgbanwe ihe mejupụtara, nha PN junction na voltaji njikwa.
A na-eji laser diode eme ihe n'ọhịa dị ka nkwurịta okwu fiber optic, diski anya, ndị na-ebi akwụkwọ laser, nyocha laser, ihe ngosi laser (pensụl laser), wdg Ha bụ laser kachasị ukwuu n'ihe gbasara mmepụta olu. Tụkwasị na nke ahụ, lasers semiconductor nwere ngwa ngwa dị ukwuu na nhazi laser, LiDAR, nkwurịta okwu laser, ngwa agha ịme anwansị laser, ịdọ aka ná ntị laser, nduzi laser na nsochi, mgbanye na mgbawa, njikwa akpaka, ngwa nchọpụta, wdg, na-eme nnukwu ahịa.
