Njengoba ubuchwepheshe be-laser buqhubeka nokuvela, izinhlobo zemithombo ye-laser ziya ngokuya zihlukahluka. Phakathi kwazo, ibha ye-laser diode igqama ngokuphuma kwayo okuphezulu kwamandla, ukwakheka okuhlangene, nokuphatha okushisayo okuhle kakhulu, okuyenza ibe yingxenye ebalulekile emikhakheni efana nokucutshungulwa kwezimboni, ubuhle bezokwelapha, imithombo yephampu, kanye nocwaningo lwesayensi.
1. Iyini Ibha ye-Laser Diode?
Ibha ye-laser diode, eyaziwa nangokuthi i-laser diode array, iyithuluzi le-laser semiconductor enamandla amakhulu elakhiwe ngokuhlanganisa amayunithi amaningi akhipha i-laser endaweni eyodwa evamile. Ngokuvamile, iyunithi ngayinye ekhiphayo icishe ibe ngama-micrometer ayi-100 ububanzi, kuyilapho ingqikithi yobubanzi bebha bungasukela kumamilimitha ambalwa ukuya kumasentimitha. Ngenxa yokuthi amayunithi e-laser amaningi ahlelwa ngokuhambisana, amabha e-laser diode angaletha amandla aqhubekayo noma ashayekile ukusuka emashumini ama-watts kuya ngaphezu kwe-kilowatt.
2. Izici Eziyinhloko
① Ukuminyana kwamandla okuphezulu
Amabha e-laser diode ahlanganisa ama-emitters amaningi endaweni ehlangene ukuze alethe amandla aphezulu kakhulu, awenze alungele izinhlelo zokusebenza ezidinga amanani amakhulu wamandla.
② Ukuphathwa Okushisayo Okuhle Kakhulu
Isakhiwo sebha sihambisana nobuchwepheshe bokupakisha obuhlukahlukene, obufana ne-AuSn (igolide-tin), i-all-indium, ne-hybrid packaging, ethuthukisa ukunqanyulwa kokushisa, inwebe ubude bedivayisi, futhi iqinisekise ukusebenza okuzinzile kwesikhathi eside.
③ Ama-Wavelengths enziwe ngendlela oyifisayo
Ngokuya ngohlelo lokusebenza, imigoqo ye-laser diode ingakhelwa amaza ahlukene okusebenza, njenge-808 nm, 915 nm, 940 nm, kanye ne-976 nm. Ukwenziwa ngokwezifiso kwe-wavelength okukhethekile nakho kuyatholakala ukuze kuhlangatshezwane nezidingo ezithile zezinto ezihlukahlukene kanye nezinhlelo.
④ Flexible Beam Shaping
Nakuba ikhwalithi ye-beam yama-laser diode bar ngokuvamile iphansi kunaleyo yama-lasers emodi eyodwa, izakhi ezibonakalayo ezifana ne-lens arrays, i-fiber coupling, nezinhlelo zamalensi amancanyana zingasetshenziswa ukuze zingqubuzane noma zigxilise ugongolo, kuthuthukise ukuhlanganisa nokuvumelana nezimo ezinhlelweni zokusebenza zesistimu.
3. Izinkambu Zokusebenza
① Ukukhiqiza Kwezimboni
Isetshenziswa ekushiseleni ipulasitiki, ukwelashwa kokushisa kwensimbi, ukuhlanzwa nge-laser, nokumaka, amabha e-laser diode anikeza isilinganiso esihle kakhulu sokusebenza kwezindleko ezinhlelweni ezidinga imithombo ye-laser enamandla amakhulu.
② Ezokwelapha kanye Nobuhle
Isibonelo, imigoqo ye-laser diode engu-808 nm isetshenziswa kakhulu kumadivayisi okususa izinwele nge-laser. Banikeza amandla aphezulu kanye nokujula kokungena okuphakathi, babhubhise ngokuphumelelayo izinwele zezinwele ngaphandle kokulimaza izicubu ezizungezile.
③ Imithombo yephampu yama-Fiber Lasers
Ezinhlelweni ze-laser ye-fiber enamandla amakhulu, imigoqo ye-laser diode ivamise ukusetshenziswa njengemithombo yephampu ukuze kujabulise i-Yb-doped noma i-Er-doped fibers, edlala indima ebalulekile ekwakheni amasistimu e-laser anamandla amakhulu.
④ Ucwaningo Lwesayensi Nokuvikela
Amabha e-laser diode nawo asetshenziswa kabanzi kubuchwepheshe obuthuthukisiwe obufana nokuhlolwa kwe-physics yamandla aphezulu, i-LiDAR, nokuxhumana nge-laser, ngenxa yokuphuma kwayo okuzinzile kanye nezakhiwo ezingenziwa ngokwezifiso.
Njengoba izidingo zokusebenza zezinhlelo ze-laser ziqhubeka nokukhuphuka, imigoqo ye-laser diode iguqukela emandleni aphezulu, ukwethembeka okukhulu, izici zefomu ezincane, kanye nezindleko eziphansi. Njengengxenye eyinhloko ezinhlelweni zokusetshenziswa kwe-laser, imigoqo ye-laser diode yamukelwa kabanzi kuzo zonke izinkambu zobuchwepheshe obuphezulu. Ngokuthuthuka kwezobuchwepheshe okuqhubekayo kanye nochungechunge lwemboni olukhula ngokukhula, imigoqo ye-laser diode kulindeleke ukuthi ijabulele amathuba emakethe abanzi futhi ibambe iqhaza elibaluleke kakhulu esikhathini esizayo.
