Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe kanye nokwanda kwezinkambu ezahlukene zohlelo lokusebenza,i-laserubuchwepheshe bokucubungula bungena kancane kancane kuzo zonke izindlela zokuphila futhi bube ithuluzi elibalulekile lokucubungula. Ekusetshenzisweni kwama-laser,i-MOPA yezinga le-kilowattAma-laser (i-Master Oscillator Power-Amplifier) asetshenziswa kabanzi emikhakheni efana nokucubungula izinto kanye nokuhlolwa kocwaningo lwesayensi ngenxa yamandla awo aphezulu, ukungena okunamandla, kanye nomthelela ophansi wokushisa. Ayithuluzi elibalulekile lokusiza amabhizinisi ukuthuthukisa ikhwalithi nokukhulisa umkhiqizo. Ithuluzi elifanele lokusebenza kahle. Kodwa ngenxa yamandla alo aphezulu, ukuze kwandiswe ukusebenza kahle kokucubungula kwe-laser ye-MOPA esezingeni le-kilowatt, ukukhethwa kwezesekeli kubalulekile. Kuphela ngokukhetha izesekeli ze-laser ezifanele lapho singaqinisekisa khona ukuthi i-laser ingasebenza ngokuzinzile nangokuphumelelayo futhi ihlangabezane kangcono nezidingo ezahlukene zohlelo lokusebenza.
Ukuqina kwamandla aphezulu
Ukukhiqizwa okukhulu kwe-MOPA esezingeni le-kilowatt enezinkomba zokusebenza okuphezulu kanye nobuchwepheshe
Ikhono lokukhiqiza ngobuningi ngokuzinzileamalaser emodi eyodwa ye-MOPA enezinga le-kilowattkuyinkomba ebalulekile ye-MOPA laser R&D yenkampani, ukukhiqiza kanye namakhono okukhiqiza. I-MAVEN okwamanje inezinhlobo eziningi zemishini yokuhlanza i-MOPA fiber laser enamandla amakhulu engahlangabezana nezidingo zokucubungula zezinhlelo zokusebenza ezahlukahlukene ngobukhulu obuhlukahlukene.
Ukuguquguquka kokukhipha amandla okugcwele kwamahora angama-24 kungaphansi kuka-<3%
Ikhwalithi yogongolo ingalawuleka
Umsebe we-Gaussian wemodi eyodwa Umqadi oyisicaba wemodi eminingi
Ubuchwepheshe bokuxhumanisa isignali yokuphela kwephampu, ukusatshalaliswa kwezinga lamandla elicwengekile kakhulu nelinengqondo, inqubo ehlukile yokuhlanganisa ukukhiqiza, kanye ne-isolator enamandla aphezulu yemodi eyodwa enekristalu ekhanyayo ngokushisa okuhle kakhulu, kuyilapho amandla okukhipha efinyelela ku-1000W, ingaqinisekisa nekhwalithi yeBeam enhle kakhulu.
Emkhakheni wokucubungula i-fiber laser, ikakhulukazi ukucutshungulwa kwe-i-laser ye-fiber ye-MOPA enamandla aphezulu, ngenxa yamandla ayo aphezulu, amandla amakhulu okushaya kwenhliziyo kanye nemvamisa ephezulu, ukukhethwa kwezesekeli kubaluleke kakhulu. Izesekeli eziyinhloko ezithinta umphumela wokucubungula we-laser yokushaya kwenhliziyo enamandla aphezulu zifaka phakathi i-Scanning galvanometer, i-focused field mirror kanye ne-reflector.
Ungayikhetha kanjani i-galvanometer yokuskena?
Umgomo wobuchwepheshe bokuskena i-galvanometer ukuqedela imisebenzi yokuskena ngesivinini esikhulu nangokunembile. Kunezici ezimbili eziyinhloko zokunquma. Esinye uhlelo lokulawula olungafinyelela isivinini esikhulu kanye nokunemba okuphezulu, kanti esinye i-galvanometer enesivinini sokuphendula esisheshayo. Isakhiwo se-galvanometer sakhiwe kakhulu izingxenye ezintathu: i-reflector, i-motor kanye ne-drive card, phakathi kwazo ilensi ibalulekile ekuzinzeni kokucutshungulwa.
Izinto zelensi ye-Galvanometer kanye nezinkomba ezithonyayo
Uhlelo lokuphatha ukushisa lweukuskena i-galvanometerfuthi kuyisici esibalulekile ekuqinisekiseni ukuzinza kokucubungula isikhathi eside. Ukwehluka kwezinga lokushisa kuzokwenza i-galvanometer ikhukhuleke futhi yehlise ukunemba kokubeka. Amanani ajwayelekile alandelayo. Ngokuphola kwamanzi, ukushabalalisa ukushisa okusebenzayo, ukuzinza kokucubungula isikhathi eside kungathuthukiswa ngo-30%.
Inani elijwayelekile lokushisa lokukhukhuleka kwe-galvanometer
Idivayisi yokupholisa amanzi ingasusa ukushisa ngempumelelo futhi iqinisekise ukusebenza okuzinzile kwesikhathi eside kwe-galvanometer. Izindlela zobuchwepheshe eziyinhloko ukuthola insimu yamanzi okupholisa eguquguqukayo ephansi ngokuklama okwenziwe kahle kwesiteshi samanzi okupholisa, kanye nokuklama isakhiwo sedivayisi yokushintshanisa ukushisa yangaphandle esebenza kahle.
Kuhlelo lwe-laser lwe-MOPA pulse olunamandla aphezulu olusezingeni le-kilowatt, sincoma kakhulu ukusetshenziswa kwamalensi e-quartz asezingeni eliphezulu kanye nezinhlelo ze-galvanometer ezinezinhlelo zokupholisa amanzi.
Ungakhetha kanjani ilensi yensimu yokugxila?
Ilensi yasensimini igxila umsebe we-laser ohlanganisiwe endaweni ethile, yandisa ubuningi bamandla omsebe we-laser, futhi isebenzisa amandla aphezulu e-laser ukwenza ukucubungula izinto ezahlukahlukene njengokusika, ukumaka, ukushisela, ukuhlanza kanye nokwelashwa kwendawo.
Izici eziyinhloko ezithinta ikhwalithi yokucubungula kanye nomphumela welensi yasensimini yizinto ezisetshenziswa yilensi yasensimini kanye nokuphakama kwendandatho ye-adaptha. Izinto eziyinhloko zelensi yasensimini yingilazi ne-quartz. Umehluko phakathi kwalokhu okubili usemphumela welensi yokushisa emandleni aphezulu. Ngemva kokuba ilensi yasensimini yokugxila ihlale ikhanyiswe yi-laser beam isikhathi eside, izokhiqiza ukuguqulwa kokushisa ngenxa yokwanda kwezinga lokushisa, okuzobangela ama-transmission optics. Inkomba yokukhanya kwento kanye nesiqondiso sokukhanya kwento ekhanyayo yokukhanya iyashintsha, kanye nomphumela welensi yokushisa uzothinta imodi ye-laser kanye nendawo yokugxila ngemva kokugxila, okuzothinta kakhulu umphumela wokucubungula. I-Quartz ine-coefficient yokukhulisa ukushisa ephansi kanye nokudlulisa okuphezulu, okwenza kube ukukhetha okungcono kwezinto ezisetshenziswayo zamalensi asensimini enamandla aphezulu. Uma kudingeka, imodyuli yokupholisa amanzi kumele ingezwe.
Indandatho ye-adaptha yokufanisa ilensi yasensimini ne-galvanometer nayo iyisici esibalulekile esithinta imishini kanye nokucubungula. Ukuphakama okufanele kwendandatho ye-adaptha kungagwema iphuzu lokubuyela kwelensi yasensimini futhi kuqinisekise ifomethi yokucubungula. Uma iphakeme kakhulu noma iphansi kakhulu, izobangela izinkinga ezifanayo.
Ezinhlelweni ze-laser ze-MOPA pulse ezisebenza ngamandla aphezulu ezingeni le-kilowatt, sincoma kakhulu ukusetshenziswa kwezibuko ze-quartz zekhwalithi ephezulu ezinamamojula okupholisa amanzi kanye nendandatho ye-adapter yesibuko sensimu enikezelwe ukuphakama okufanele.
Ungawafanisa kanjani amalensi abonisa ukukhanya?
Umsebenzi oyinhloko wamalensi abonakalisayo esakhiweni sendlela yokukhanya ukushintsha indlela yendlela yokukhanya. Ukukhetha amalensi abonakalisayo asezingeni elihle kanye nezindlela zokufaka ezijwayelekile kungadlala indima enkulu kwezinye izinhlelo zokusebenza ezikhethekile, kodwa amalensi asezingeni eliphansi kanye nezindlela zokufaka ezingenangqondo nazo zizobangela umbuzo omusha. Izici zezinto ezibonakalayo zelensi zinqunywa ubude be-wavelength kanye namandla e-laser. I-substrate ngokuvamile yenziwe nge-quartz ehlanganisiwe noma i-silicon ekristalu. Ifilimu ebonakalisayo ye-laser ngokuvamile yenziwe ngefilimu yesiliva noma ifilimu ye-dielectric esobala, enokukhanya okuphezulu, izinga eliphansi lokumuncwa kanye nokumelana ne-laser. Izici zomkhawulo womonakalo ophezulu.
Isibukisi sendiza esifanele ngeke sithinte ikhwalithi yokugxila, kodwa ekusetshenzisweni kwangempela, indiza yokubonakalisa ingase ikhubazeke ngenxa yezici zokucindezeleka njengokuqina kwezikulufo, okufana nesibuko esiyisilinda. Ukuphambuka kuthinta kakhulu ikhwalithi yendawo yokugxila, okubangela i-astigmatism ephansi kanye nokunye i-astigmatism ephansi. Ukuphambuka kuvimbela indawo egxile ekufinyeleleni umkhawulo wokusabalalisa, okuthinta ikhwalithi yokucubungula kanye nomphumela.
Ezinhlelweni ze-laser ze-MOPA pulse ezinamandla aphezulu ezingeni le-kilowatt, sincoma kakhulu ukusetshenziswa kwezibonisi ze-quartz zekhwalithi ephezulu kanye nezindlela zokufaka ezifanele ukuqinisekisa ukuthi amalensi anamandla ngaphandle kokuguquka.
