Incazelo ye-leser ye-laser ehlanganisiwe, imigomo yokusebenza, kanye ne-wavelength ejwayelekile
I-leser diode ye-leser ehlanganisiwe iyithuluzi le-semiconductor elikhiqiza ukukhanya okubumbene, okuleso sikhathi okugxile futhi kuqondaniswe kahle ukuthi kuhlanganiswe nentambo ye-fiber optic. Isimiso esiyisisekelo sibandakanya ukusebenzisa amanje kagesi ukukhuthaza i-dide, ukudala ama-photon ngokusebenzisa ukuphuma okuvuselelayo. Lezi zithombe zikhuliswa ngaphakathi kwe-diode, zikhiqiza ugongolo lwe-laser. Ngokugxila ngokucophelela nangokuqondanisa, lo mculo we-laser uqondiswe emgogodleni wekhebula le-fiber optic, lapho kudluliswa khona ngokulahleka okuncane ngokukhombisa kwangaphakathi okuphelele.
Ububanzi be-wavelength
I-wavelength ejwayelekile yemodyuli ye-laser diode ehlanganisiwe ye-fiber Ngokuvamile, lawa madivayisi angamboza uhla olubanzi lwama-wavelength, kufaka phakathi:
I-Spectrum ebonakalayo ebonakalayo:Esukela ku-400 nm (violet) kuya ku-700 nm (ebomvu). Lokhu kuvame ukusetshenziswa kuzinhlelo zokusebenza ezidinga ukukhanya okubonakalayo ukuze kukhanye, ukubonisa, noma ukuzwela.
Eduze-infrared (NIR):Esukela cishe ngo-700 nm kuya ku-2500 nm. Ama-Navelthths we-NIR asetshenziswa kakhulu ekuxhumaneni ngocingo, izinhlelo zokusebenza zezokwelapha, nezinqubo ezahlukahlukene zezimboni.
Mid-infrared (MIR): Ukunwebeka ngaphesheya kwe-2500 NM, yize kuvame kakhulu kumamojula ajwayelekile we-laser diodi ehlanganisiwe ngenxa yezinhlelo zokusebenza ezikhethekile nezinto zokwenziwa zefayibha ezidingekayo.
I-Lumispot Tech inikezela nge-module ye-Laser Diode ehlanganiswe ne-laser'Izidingo zohlelo lokusebenza.
Ejwayelekile aukuhlaselas yama-lasers ahlanganiswe ne-fiber kuma-wavelength ahlukene
Lo mhlahlandlela uhlola indima ebaluleke kakhulu ye-Laser-Couped ye-Laser Diodes (LDS) ekuthuthukiseni ubuchwepheshe bomthombo wamaphampu nezindlela zokupompa zokubona ezinhlelo ezahlukahlukene ze-laser. Ngokugxila kuma-wavelength athile kanye nezinhlelo zawo, sigqamisa ukuthi lezi zifo ze-Laser Diade ziguqula kanjani ukusebenza kanye nokusetshenziswa kwazo zombili ama-lasers ama-fiber kanye nama-lood-State Lasers.
Ukusetshenziswa kwama-lasers ahlanganiswe ne-fiber njengemithombo yamaphampu ye-fiber lasers
I-915NM ne-976NM fiber ehlanganisiwe i-LD njengomthombo wephampu we-10640NM fiber laser.
Nge-fiber lasers esebenza ku-1064NM ebangeni le-1064NM, imikhiqizo esebenzisa ama-wavelength ka-915nm kanye ne-976NM ingasebenza njengemithombo yamaphampu ephumelelayo. Lokhu kuqashwe ngokuyinhloko kuzinhlelo zokusebenza ezinjengokusika kwe-laser kanye nokushiswa, ukungcola, ukucubungula kwe-laser, ukumaka, kanye nezikhali ze-laser eziphakeme. Inqubo, eyaziwa ngokuthi ukupompa ngqo, ifaka i-fiber edonsa isibani sepompo futhi isilikhipha ngokuqondile njengomphumela we-laser kuma-wavelength afana ne-10640NM, ne-1080NM, ne-1080NM, ne-1080NM, ne-1080NM. Le ndlela yokupompa isetshenziswa kabanzi kuwo womabili ama-lasers acwaninga kanye nama-lasers ajwayelekile wezimboni.
I-fiber ehlanganisiwe ye-laser diode ene-940NM njengomthombo wephampu we-1550nm fiber laser
Esikhathini sawo-Realm we-1550nm fiber lasers, ama-laser ase-fiber-ahlanganisiwe ane-940NM wavenweth evame ukusetshenziswa njengemithombo yamaphampu. Lolu hlelo lokusebenza lubaluleke ikakhulukazi emkhakheni weLaser Lidar.
Ukusetshenziswa okukhethekile kwe-fiber kuhlanganisiwe ye-laser diode nge-790NM
Ama-lasers ahlanganiswe ne-fiber ku-790nm awagcini nje kuphela njengemithombo yamaphampu ye-fiber lasers kodwa ayasebenza nama-lasers aqinile wombuso. Zisetshenziswa ikakhulukazi njengemithombo yamaphampu yama-lasers asebenza eduze kwe-1920NM wavethth, ngezicelo eziyinhloko zokuphikisa nge-photoelectric.
Izinjaof ama-lasers ahlanganiswe ne-fiber njengemithombo yamaphampu ye-laser eqinile yombuso
Kuma-Lasers aqinile akhipha phakathi kuka-355nm no-532NM, ama-laserlers ahlanganiswe ne-fiber anezikhathi ezingama-808NM, 880NM, 888NM, kanti u-888nm zikhethwa. Lokhu kusetshenziswa kabanzi ocwaningweni lwesayensi nasekuthuthukisweni kwama-lasers aqinile wombuso ku-violet, eluhlaza okwesibhakabhaka, kanye ne-green spectrum.
Izicelo eziqondile ze-Semiconductor Lasers
Izicelo eziqondile ze-Semiconductor Laser ezibandakanya umphumela oqondile, ukuhlanganiswa kwelensi, ukuhlanganiswa kwebhodi lesekethe, kanye nokuhlanganiswa kohlelo. Ama-lasers ahlanganiswe ne-fiber anama-waveleng afana ne-450nm, 525nm, 650nm, 790nm, 815nm asetshenziswa kuzinhlelo ezahlukahlukene kufaka phakathi ukukhanyiswa, ukuhlolwa komshini, umbono womshini kanye nezinhlelo zokuphepha.
Izidingo zoMthombo wePumpu we-fiber lasers nama-lasers aqinile wombuso.
Ukuqonda okuningiliziwe kwezidingo zomthombo we-fiber ze-fiber lasers kanye nama-lasers aqinile, kubalulekile ukuze ungene ekucacisweni kokuthi la ama-lasers asebenza kanjani nendima yemithombo yepompo ekusebenzeni kwawo. Lapha, sizokwanda ekubukeni kokuqala ukumboza izinkampani zezinqubo zokupompa, izinhlobo zemithombo yamaphampu esetshenzisiwe, kanye nomthelela wazo ekusebenzeni kwe-laser. Ukukhetha nokucushwa kwemithombo yamaphampu kube nomthelela ngqo ekusebenzeni kwe-laser, amandla okukhipha, kanye nekhwalithi ye-beam. Ukuhlangana okusebenzayo, ukufana kwe-wavengethth, kanye nokuphathwa kwe-thermal kubalulekile ukwenza kahle ukusebenza kanye nokunweba isikhathi sokuphila kwe-laser. Intuthuko kubuchwepheshe be-Laser Diode Const ukuthuthukisa ukusebenza kanye nokwethenjwa kwazo zombili ama-lasers kanye nama-lasers aqinile, azenze aguquguquke ngokwengeziwe futhi abize izindleko zohlobo oluthile lwezicelo.
- Izidingo zomthombo we-fiber lasers pump
I-Laser DiodesNjengemithombo yepompo:Ama-lears we-fiber asebenzisa kakhulu ama-laser diodes njengomthombo wawo wepompo ngenxa yokusebenza kwawo, usayizi ohlangothini, kanye nekhono lokukhiqiza isibani esithile sokukhanya okufana ne-fope fiber. Ukukhethwa kwe-laser diode waveledth kubalulekile; Isibonelo, i-dopant ejwayelekile e-Fibre Lasers yi-YTterbium (YB), enesilinganiso esisezingeni eliphakeme sokutholwa cishe ngo-976 nm. Ngakho-ke, ama-laser diode akhipha noma eduze kwale wavelength ancamela ukupompa ama-yb-doped fiber lasers.
Idizayini yefiber egqoke kabili:Ukwandisa ukusebenza kahle kokumuncwa kokukhanya kusuka ku-Pump Laser Diodes, ama-lasers e-fiber ajwayele ukusebenzisa ukwakheka kwefayibha e-Double-Clad. Umgogodla wangaphakathi uphokodliwe nge-laser medium (isib. Umgogodla umunca ukukhanya kwepompo futhi ukhiqize isenzo se-laser, ngenkathi ukucwazimula kuvumela inani elibaluleke kakhulu lokukhanya kwepompo ukuxhumana nomgogodla, okwenza ngcono ukusebenza kahle.
I-Wavevelength ihambelana nokusebenza kahle kokuhlangana: Ukupompa okusebenzayo akudingi nje kuphela ukukhetha ama-laser diode ane-wavelength efanelekile kepha futhi nokwenza kahle ukusebenza kahle kokuhlangana phakathi kwama-diode nefayibha. Lokhu kufaka phakathi ukuqondanisa ngokucophelela kanye nokusetshenziswa kwezakhi ze-optical ezifana namalensi kanye nama-coupler ukuqinisekisa ukukhanya kwepompo ephezulu kufakwa emgogodleni noma okhalweni.
-Ama-lasers aqinile wombusoIzidingo zomthombo wepompo
Ukupompa Optical:Ngaphandle kwe-laser diodes, ama-laser-state ama-lasers (kufaka phakathi ama-lasers amaningi afana ne-ND: i-yag) angaphonswa amalambu akhanyayo noma izibani ze-arc. Lawa amalambu akhipha isibukeli esibanzi sokukhanya, okuyingxenye yalokho okuhambisana nama-band amunculity we-laser medium. Ngenkathi isebenza kahle kune-Laser Diode Pumpeling, le ndlela inganikeza amandla aphezulu we-pulse, okwenza kube lula ukuthola izinhlelo zokusebenza ezidinga amandla aphezulu.
Ukucushwa komthombo wempompo:Ukucushwa komthombo wamaphampu kuma-lasers aqiniswe ngokuqinile kungathinta kakhulu ukusebenza kwawo. Ukupompa ekugcineni nokupompa oseceleni kungukucushwa okuvamile. Ukuphela kokuphenya, lapho ukukhanya kwepompo kuqondiswe eksishini ebonakalayo ye-laser medium, kunikeza ukugqagqana okungcono phakathi kokukhanya kwepompo nemodi ye-laser, okuholela ekusebenzeni okuphezulu. Ukuphompana, ngenkathi kungenzeka ukuthi kusebenze kahle, kulula futhi kunganikeza amandla aphezulu aphelele ezinduku ezinkulu noma ama-slabs.
Ukuphathwa kwe-Thermal:Zombili lezi zelasi ze-fiber ne-solid-State zidinga ukuphathwa okusebenzayo okushisayo ukuphatha ukushisa okwenziwe yimithombo yamaphampu. E-fiber lasers, indawo enwetshiwe ye-fiber aids ekuhlaselweni kokushisa. Ku-Lasers eqinile, izinhlelo zokupholisa (ezinjengokuphola kwamanzi) ziyadingeka ukuze zilondoloze ukusebenza okuzinzile futhi zivikele i-thermal lensing noma ukulimala kwe-laser media.
