Njengoba ubuchwepheshe be-laser buqhubeka nokukhula, izinhlobo zemithombo ye-laser ziyahlukahluka kakhulu. Phakathi kwazo, ibha ye-laser diode ivelele ngokukhipha kwayo amandla aphezulu, isakhiwo sayo esincane, kanye nokuphathwa kokushisa okuhle kakhulu, okwenza ibe yingxenye ebalulekile emikhakheni efana nokucubungula izimboni, ubuhle bezokwelapha, imithombo yamaphampu, kanye nocwaningo lwesayensi.
1. Iyini i-Laser Diode Bar?
Ibha ye-laser diode, eyaziwa nangokuthi i-laser diode array, iyidivayisi ye-laser ye-semiconductor enamandla amakhulu eyakhiwe ngokuhlanganisa amayunithi amaningi akhipha i-laser ku-substrate eyodwa evamile. Ngokuvamile, iyunithi ngayinye ekhiphayo ingaba ama-micrometer ayi-100 ububanzi, kuyilapho ububanzi obuphelele bebha bungasukela kumamilimitha amaningana kuya kumasentimitha. Ngenxa yokuthi amayunithi amaningi e-laser ahlelwe eceleni, amabha e-laser diode angaletha amandla aqhubekayo noma aqhutshwayo kusukela kumashumi ama-watts kuya ngaphezu kwe-kilowatt.
2. Izici Eziyinhloko
① Ubuningi Bamandla Aphezulu
Amabha e-laser diode ahlanganisa ama-emitter amaningi endaweni encane ukuze alethe amandla aphezulu kakhulu, okwenza abe afanele izinhlelo zokusebenza ezidinga amandla amaningi.
② Ukuphathwa Okuhle Kakhulu Kokushisa
Isakhiwo sebha siyahambisana nobuchwepheshe obuhlukahlukene bokupakisha, njenge-AuSn (i-gold-tin), i-all-indium, kanye nokupakisha okuhlanganisiwe, okuthuthukisa ukushabalaliswa kokushisa, kwandise isikhathi sokuphila kwedivayisi, futhi kuqinisekise ukusebenza okuzinzile kwesikhathi eside.
③ Ubude Bamagagasi Obungenziwa Ngokwezifiso
Kuye ngohlelo lokusebenza, imigoqo ye-laser diode ingaklanywa ngama-wavelength ahlukene okusebenza, njenge-808 nm, 915 nm, 940 nm, kanye ne-976 nm. Ukwenza ngokwezifiso ama-wavelength akhethekile nakho kuyatholakala ukuze kuhlangatshezwane nezidingo ezithile zezinto nezinhlelo ezahlukahlukene.
④ Ukubumba Ugongolo Oluguquguqukayo
Nakuba ikhwalithi yemisebe yemigoqo ye-laser diode ngokuvamile iphansi kuneye-laser yemodi eyodwa, izingxenye ze-optical ezifana nama-lens arrays, i-fiber coupling, kanye nezinhlelo ze-micro-lens zingasetshenziswa ukuhlanganisa noma ukugxila i-beam, okuthuthukisa ukuhlanganiswa kanye nokuguquguquka kwezinhlelo zokusebenza zesistimu.
3. Izinkambu Zohlelo Lokusebenza
① Ukukhiqiza Kwezimboni
Amabha e-laser diode asetshenziswa ekushiseleni ngepulasitiki, ekwelashweni kokushisa kwensimbi, ekuhlanzweni nge-laser, nasekumakeni, anikeza isilinganiso esihle kakhulu sokusebenza kwezindleko ezinhlelweni ezidinga imithombo ye-laser enamandla aphezulu.
② Ezokwelapha Nobuhle
Isibonelo, imigoqo ye-laser diode engu-808 nm isetshenziswa kabanzi kumadivayisi okususa izinwele nge-laser. Inikeza amandla aphezulu kanye nokujula okuphakathi kokungena, ibhubhisa ngempumelelo ama-follicle ezinwele ngaphandle kokulimaza izicubu ezizungezile.
③ Imithombo Yephampu Yama-Fiber Lasers
Ezinhlelweni ze-laser yefayibha enamandla amakhulu, imigoqo ye-laser diode ivame ukusetshenziswa njengemithombo yokuphampa ukuze kukhuthazwe imigoqo ye-Yb-doped noma ye-Er-doped, edlala indima ebalulekile ekwakheni izinhlelo ze-laser ezinamandla amakhulu.
④ Ucwaningo Lwesayensi Nokuzivikela
Amabha e-laser diode asetshenziswa kabanzi kwezobuchwepheshe obuthuthukisiwe njengokuhlolwa kwefiziksi yamandla aphezulu, i-LiDAR, kanye nokuxhumana nge-laser, ngenxa yomkhiqizo wawo ozinzile kanye nezakhiwo zawo ezingenziwa ngezifiso.
Njengoba izidingo zokusebenza kwezinhlelo ze-laser ziqhubeka nokukhuphuka, imigoqo ye-laser diode iguqukela emandleni aphezulu, ukuthembeka okukhulu, izici ezincane zesimo, kanye nezindleko eziphansi. Njengengxenye ebalulekile ezinhlelweni zohlelo lokusebenza lwe-laser, imigoqo ye-laser diode isetshenziswa kabanzi emikhakheni yobuchwepheshe obuphezulu. Ngokuthuthuka okuqhubekayo kwezobuchwepheshe kanye nochungechunge lwemboni olukhula ngokuvuthwa, imigoqo ye-laser diode kulindeleke ukuthi ijabulele amathuba emakethe abanzi futhi ithathe indima ebaluleke kakhulu esikhathini esizayo.
