Diode laser o se masini fa'aeletoroni e fa'aogaina se PN fa'atasi ma mea fa'ameamea semiconductor binary po'o ternary.Pe a faʻaaogaina se voltage i fafo, e faʻafeiloaʻi le eletise mai le faʻaulu faʻaulu i le valence band ma faʻasaʻo le malosi, ma maua ai photons.Pe a fa'aalia pea nei photons i le PN junction, o le a latou pa'u mai se laisa malosi.Semiconductor lasers o loʻo i ai uiga o le miniaturization ma le maualuga o le faʻatuatuaina, ma e mafai ona fetuʻunaʻi a latou laser e ala i le suia o le meafaitino, PN junction size, ma le pulea o le voltage.
Diode lasers e fa'aaogaina lautele i fanua e pei o le fiber optic communication, optical discs, laser printers, laser scanners, laser indicators (laser penis), ma isi. O le laser sili ona tele i tulaga o le gaosiga o le voluma.E le gata i lea, o le semiconductor lasers e tele faʻaoga i le laser ranging, LiDAR, fesoʻotaʻiga leisa, auupega faʻataʻitaʻi leisa, lapataiga leisa, taʻiala leisa ma le siakiina, faʻamalama ma le paʻu, faʻatautaia otometi, meafaifaʻaili, ma isi, faʻavaeina se maketi lautele.
