Njengendlela yokuhlanza ephumelelayo neyobungani nemvelo,ubuchwepheshe bokuhlanza nge-laserkancane kancane ithatha indawo yezindlela zokuhlanza ngamakhemikhali zendabuko kanye nokuhlanza ngemishini. Njengoba izidingo zokuvikela imvelo zezwe ziya ngokuya ziqina kanye nokuphishekela okuqhubekayo ikhwalithi yokuhlanza kanye nokusebenza kahle emkhakheni wokukhiqiza wezimboni, isidingo semakethe sobuchwepheshe bokuhlanza nge-laser sikhula ngokushesha. Njengezwe elikhulu lokukhiqiza, iShayina inesizinda esikhulu sezimboni, esinikeza isikhala esibanzi sokusetshenziswa kabanzi kobuchwepheshe bokuhlanza nge-laser. Ezindiza, ezokuthutha ngezitimela, ezokukhiqiza izimoto, ezokukhiqiza isikhunta kanye nezinye izimboni, ubuchwepheshe bokuhlanza nge-laser busetshenziswe kabanzi futhi buyanda kancane kancane kwezinye izimboni.
Ubuchwepheshe bokuhlanza ubuso bezinto zokusebenza busetshenziswa kabanzi emikhakheni eminingi. Izindlela zokuhlanza zendabuko zivame ukuhlanza ngokuxhumana, okusebenzisa amandla omshini ebusweni bento ezohlanzwa, okonakalisa ubuso bento noma indawo yokuhlanza inamathela ebusweni bento ezohlanzwa futhi ayikwazi ukususwa. , okubangela ukungcola kwesibili. Namuhla, izwe likhuthaza ukuthuthukiswa kwezimboni ezisafufusa eziluhlaza nezinobungani nemvelo, futhi ukuhlanza nge-laser kuyindlela engcono kakhulu. Indlela yokuhlanza nge-laser engagugi futhi engathintani ixazulula lezi zinkinga. Imishini yokuhlanza nge-laser ifanelekela ukuhlanza izinto zezinto ezahlukahlukene futhi ibhekwa njengendlela yokuhlanza ethembekile nephumelelayo kakhulu.
Ukuhlanzwa nge-laserisimiso
Ukuhlanzwa nge-laser kuwukukhanyisela umsebe we-laser onamandla aphezulu engxenyeni yento ezohlanzwa, ukuze i-laser imuncwe ungqimba lokungcola kanye ne-substrate. Ngezinqubo ezifana nokususa ukukhanya kanye nokuhwamuka, ukunamathelana phakathi kwezinto ezingcolisayo kanye ne-substrate kuyanqotshwa, ukuze izinto ezingcolisayo zishiye ubuso bento ukuze kufezwe injongo yokuhlanza ngaphandle kokulimaza into ngokwayo.
Umfanekiso 1: Umdwebo ohleliwe wokuhlanza nge-laser.
Emkhakheni wokuhlanza nge-laser, ama-fiber lasers abe ngumnqobi phakathi kwemithombo yokukhanya yokuhlanza nge-laser ngenxa yokusebenza kahle kokuguqulwa kwe-photoelectric okuphezulu kakhulu, ikhwalithi ye-beam enhle kakhulu, ukusebenza okuzinzile kanye nentuthuko eqhubekayo. Ama-fiber lasers amelelwa izinhlobo ezimbili: ama-pulsed fiber lasers kanye nama-fiber lasers aqhubekayo, athatha izikhundla eziholayo emakethe ekucutshungulweni kwezinto ezinkulu kanye nasekucutshungulweni kwezinto ngokunemba ngokulandelana.
Umfanekiso 2: Ukwakhiwa kwe-laser ye-fiber fiber evuvukile.
Ukuqhathanisa Isicelo Sokuhlanza I-Fiber Laser Eshukunyiswayo vs. I-Fiber Laser Eqhubekayo
Ngezinhlelo zokusebenza zokuhlanza nge-laser ezisafufusa, abantu abaningi bangase badideke kancane lapho bebhekene nama-pulse lasers nama-continuous lasers emakethe: Ingabe kufanele bakhethe ama-pulse fiber lasers noma ama-continuous fiber lasers? Ngezansi, kusetshenziswa izinhlobo ezimbili ezahlukene zama-laser ukwenza izivivinyo zokususa upende ezindaweni zezinto ezimbili, futhi kusetshenziswa amapharamitha okuhlanza nge-laser afanele kanye nemiphumela yokuhlanza elungiselelwe ukuqhathanisa.
Ngokubuka okuncane kakhulu, insimbi eshidi incibilikile ngemuva kokucutshungulwa nge-laser ye-fiber eqhubekayo enamandla amakhulu. Ngemva kokuba insimbi icutshungulwe yi-laser ye-fiber ye-MOPA pulse, izinto eziyisisekelo zonakele kancane futhi ukuthungwa kwezinto eziyisisekelo kuyagcinwa; ngemva kokuba insimbi icutshungulwe yi-laser ye-fiber eqhubekayo, kukhiqizwa umonakalo omkhulu kanye nezinto ezincibilikisiwe.
I-MOPA pulsed fiber laser (kwesobunxele) I-CW fiber laser (kwesokudla)
I-laser yefayibha evuvukele (kwesobunxele) I-laser yefayibha eqhubekayo (kwesokudla)
Kusukela ekuqhathanisweni okungenhla, kungabonakala ukuthi ama-laser e-fiber aqhubekayo angabangela kalula ukushintsha kombala kanye nokuguquka kwe-substrate ngenxa yokufaka kwawo ukushisa okukhulu. Uma izidingo zomonakalo we-substrate zingekho phezulu futhi ubukhulu bezinto ezizohlanzwa buncane, lolu hlobo lwe-laser lungasetshenziswa njengomthombo wokukhanya. I-laser ye-fiber ecindezelwe ithembele emandleni aphezulu kanye nama-frequency pulses aphezulu ukuze isebenze ezintweni, futhi ishisa ngokushesha futhi i-oscillate izinto zokuhlanza ukuze izisuse; inemiphumela emincane yokushisa, ukuhambisana okuphezulu, kanye nokunemba okuphezulu, futhi ingafeza imisebenzi eyahlukahlukene. Ibhubhisa izici ze-substrate.
Kusukela kulesi siphetho, ngenxa yokunemba okuphezulu, kuyadingeka ukulawula ngokuqinile ukuphakama kwezinga lokushisa le-substrate, futhi ezimweni zokusetshenziswa ezidinga ukuthi i-substrate ingabi yingozi, njenge-aluminium ependiwe kanye nensimbi yesikhunta, kunconywa ukukhetha i-laser ye-pulse fiber; kwezinye izinto ezinkulu ze-aluminium alloy ezinamandla aphezulu, amapayipi anomumo oyindilinga, njll. Ngenxa yobukhulu bawo obukhulu kanye nokushabalaliswa kokushisa okusheshayo, kanye nezidingo eziphansi ekulimaleni kwe-substrate, ama-laser e-fiber aqhubekayo angakhethwa.
In ukuhlanzwa nge-laser, izimo zezinto zokwakha zidinga ukucatshangelwa ngokuphelele ukuqinisekisa ukuthi izidingo zokuhlanza ziyahlangatshezwana ngenkathi kunciphisa umonakalo ku-substrate. Ngokwezimo zokusebenza zangempela, kubalulekile ukukhetha umthombo wokukhanya we-laser ofanele.
Uma ukuhlanzwa kwe-laser kufuna ukungena ekusetshenzisweni okukhulu, akunakuhlukaniswa nokusungulwa kobuchwepheshe obusha nezinqubo ezintsha. I-Maven izoqhubeka nokunamathela ekubekweni kwe-laser +, ilawule ijubane lentuthuko kancane kancane, ilwele ukujulisa ubuchwepheshe bomthombo wokukhanya we-laser oyinhloko, futhi igxile ekuxazululeni izinto ezibalulekile ze-laser kanye nezinkinga ezibalulekile zezingxenye zinikeza umthombo wamandla wokukhiqiza okuthuthukile.
