I-laser ye-diode iyithuluzi likagesi elisebenzisa i-PN junction enezinto ze-semiconductor ezimbili noma ezintathu. Uma i-voltage isetshenziswa ngaphandle, ama-electron ashintsha esuka ebhendini lokuhambisa aye ebhendini le-valence bese ekhipha amandla, ngaleyo ndlela akhiqize ama-photon. Lapho la ma-photon ephinda ebonakala e-PN junction, azoqhumisa umsebe we-laser oqinile. Ama-laser e-semiconductor anezici ze-miniaturization kanye nokuthembeka okuphezulu, futhi imvamisa yawo ye-laser ingalungiswa ngokushintsha ukwakheka kwezinto, usayizi we-PN junction, kanye ne-voltage yokulawula.
Ama-laser e-diode asetshenziswa kabanzi emikhakheni efana nokuxhumana kwe-fiber optic, ama-disc optical, amaphrinta e-laser, ama-laser scanner, izinkomba ze-laser (amapeni e-laser), njll. Angama-laser amakhulu kunawo wonke maqondana nomthamo wokukhiqiza. Ngaphezu kwalokho, ama-laser e-semiconductor anezinhlelo zokusebenza eziningi ezinhlobonhlobo ze-laser, i-LiDAR, ukuxhumana nge-laser, izikhali zokulingisa i-laser, isixwayiso se-laser, isiqondiso se-laser kanye nokulandelela, ukusha nokuqhuma, ukulawula okuzenzakalelayo, amathuluzi okuthola, njll., okwenza imakethe ebanzi.
