I-MOPA (I-Master Oscillator Power Amplifier) Incazelo Yesakhiwo
Emkhakheni wobuchwepheshe be-laser, uhlaka lwe-Master Oscillator Power Amplifier (MOPA) lumi njengesibani sokuqanjwa kabusha, esiklanyelwe ukuletha okuphumayo kwe-laser kokubili kwekhwalithi ephezulu namandla. Lolu hlelo oluyinkimbinkimbi lwakhiwe izingxenye ezimbili ezibalulekile: I-Master Oscillator kanye ne-Power Amplifier, ngayinye idlala indima eyingqayizivele nebalulekile.
I-Master Oscillator:
Enhliziyweni yohlelo lwe-MOPA kukhona I-Master Oscillator, ingxenye ebophezelekile ekukhiqizeni i-laser enobude obuthile obukhethekile, ukuhambisana, kanye nekhwalithi ye-beam ephakeme kakhulu. Nakuba okukhiphayo kwe-Master Oscillator ngokuvamile kunamandla aphansi, ukuzinza nokunemba kwayo kwakha itshe legumbi lokusebenza kwalo lonke uhlelo.
Isikhulisamandla:
Umsebenzi oyinhloko we-Power Amplifier ukukhulisa i-laser ekhiqizwe i-Master Oscillator. Ngochungechunge lwezinqubo zokukhuliswa, ithuthukisa ngokuphawulekayo amandla ewonke we-laser ngenkathi ilwela ukugcina ubuqotho bezimpawu zomugqa wokuqala, njengobude begagasi nokuhambisana.
Uhlelo ngokuyinhloko luqukethe izingxenye ezimbili: kwesokunxele, kukhona umthombo we-laser wembewu ophumayo wekhwalithi ephezulu, futhi kwesokudla, kukhona isigaba sokuqala noma ukwakheka kwe-multi-stage optical fibre optical amplifier. Lezi zingxenye ezimbili zihlangene zakha umthombo obonakalayo we-master oscillator power amplifier (MOPA).
I-Multistage Amplification ku-MOPA
Ukuze kuqhutshekwe nokwenyusa amandla e-laser nokwandisa ikhwalithi ye-beam, amasistimu e-MOPA angase ahlanganise izigaba zokukhulisa eziningi. Isiteji ngasinye senza imisebenzi ehlukile yokukhulisa amandla, sithola ngokuhlanganyela ukudluliswa kwamandla okuphumelelayo nokusebenza okuthuthukisiwe kwe-laser.
I-Pre-amplifier:
Kusistimu yokukhulisa izigaba eziningi, i-Pre-amplifier idlala indima ebalulekile. Inikeza ukukhuliswa kokuqala ekukhishweni kwe-Master Oscillator, ilungiselela i-laser yezigaba ezilandelayo, ezisezingeni eliphezulu zokukhulisa.
I-Intermediate Amplifier:
Lesi sigaba sikhulisa amandla e-laser. Ezinhlelweni eziyinkimbinkimbi ze-MOPA, kungase kube namaleveli amaningi E-Intermediate Amplifiers, ngalinye lithuthukisa amandla kuyilapho liqinisekisa ikhwalithi ye-laser beam.
I-amplifier yokugcina:
Njengesigaba sokugcina sokukhulisa, i-Final Amplifier ikhuphula amandla e-laser afike ezingeni elifunekayo. Ukunakwa okukhethekile kuyadingeka kulesi sigaba ukuze kulawulwe ikhwalithi ye-beam nokugwema ukuvela kwemiphumela engaqondile.
Izicelo kanye nezinzuzo ze-MOPA Structure
Isakhiwo se-MOPA, esinekhono laso lokuhlinzeka ngokuphuma kwamandla aphezulu kuyilapho sigcina izici ze-laser ezifana nokunemba kwe-wavelength, ikhwalithi ye-beam, nokuma kwe-pulse, kuthola izinhlelo zokusebenza emikhakheni eyahlukene. Lokhu kubandakanya ukunemba kokucutshungulwa kwezinto, ucwaningo lwesayensi, ubuchwepheshe bezokwelapha, nokuxhumana kwe-fiber optic, ukubala okumbalwa. Ukusetshenziswa kobuchwepheshe bokukhulisa izigaba eziningi kuvumela amasistimu e-MOPA ukuthi alethe ama-laser anamandla amakhulu anokuguquguquka okuphawulekayo nokusebenza okuvelele.
I-MOPAI-Fiber LaserKusuka ku-Lumispot Tech
Ochungechungeni lwe-LSP pulse fiber laser, iI-1064nm nanosecond pulse fiber laserisebenzisa isakhiwo esithuthukisiwe se-MOPA (I-Master Oscillator Power Amplifier) esinobuchwepheshe bokukhulisa izigaba eziningi kanye nomklamo wemojuli. Ifaka umsindo ophansi, ikhwalithi ye-beam enhle kakhulu, amandla aphezulu aphezulu, ukulungiswa kwepharamitha okuguquguqukayo, nokuhlanganiswa kalula. Umkhiqizo usebenzisa ubuchwepheshe obuthuthukisiwe besinxephezelo samandla, ucindezela ngempumelelo ukuwohloka kwamandla okusheshayo ezindaweni ezishisa kakhulu nezinokushisa okuphansi, okuwenza ulungele kakhulu ukusetshenziswaI-TOF (Isikhathi Sendiza)izinkambu zokuthola.
