Ukuthuthukisai-fiber laserisakhiwo

1, isakhiwo sephampu yokukhanya kwesikhala

Ama-laser e-fiber okuqala ayesebenzisa kakhulu i-optical pump output,i-laserUkukhishwa, amandla ayo okukhipha aphansi, ukuze kuthuthukiswe ngokushesha amandla okukhipha ama-fiber lasers ngesikhathi esifushane, kuba nobunzima obukhulu. Ngo-1999, amandla okukhipha emkhakheni wokucwaninga nokuthuthukiswa kwe-fiber laser aphule ama-watts ayi-10,000 okokuqala, isakhiwo se-fiber laser ngokuyinhloko ukusetshenziswa kwe-optical bidirectional pumping, okwenza i-resonator, lapho uphenyo lokusebenza kahle kwe-slope ye-fiber laser lufinyelele ku-58.3%.
Kodwa-ke, nakuba ukusetshenziswa kobuchwepheshe bokukhanya kwephampu yefayibha kanye nokuxhumanisa i-laser ukuthuthukisa ama-fiber laser kungathuthukisa ngempumelelo amandla okukhipha ama-fiber laser, kodwa ngesikhathi esifanayo kukhona ubunzima, obungavumeli ilensi yokukhanya ukwakha indlela yokukhanya, uma i-laser idinga ukuthuthwa enkambisweni yokwakha indlela yokukhanya, khona-ke indlela yokukhanya nayo idinga ukulungiswa kabusha, okunciphisa ukusetshenziswa okubanzi kwama-fiber laser e-fiber structure ephampu yokukhanya.

2, isakhiwo se-oscillator esiqondile kanye nesakhiwo se-MOPA

Ngokuthuthuka kwama-laser e-fiber, ama-cladding power strippers ashintshe kancane kancane izingxenye zelensi, enza kube lula izinyathelo zokuthuthukiswa kwama-laser e-fiber futhi athuthukise ngokungaqondile ukusebenza kahle kokugcinwa kwama-laser e-fiber. Lo mkhuba wokuthuthukiswa ufanekisela ukusebenza kancane kancane kwama-laser e-fiber. Isakhiwo se-oscillator eqondile kanye nesakhiwo se-MOPA yizakhiwo ezimbili ezivame kakhulu zama-laser e-fiber emakethe. Isakhiwo se-oscillator eqondile ukuthi i-grating ikhetha ubude be-wavelength enkambisweni ye-oscillation, bese ikhipha ubude be-wavelength obukhethiwe, kuyilapho i-MOPA isebenzisa ubude be-wavelength obukhethwe yi-grating njengokukhanya kwembewu, futhi ukukhanya kwembewu kukhuliswa ngaphansi kwesenzo se-amplifier yezinga lokuqala, ngakho-ke amandla okukhipha e-laser ye-fiber nawo azothuthukiswa ngezinga elithile. Isikhathi eside, ama-laser e-fiber anesakhiwo se-MPOA asetshenziswe njengesakhiwo esithandwayo sama-laser e-fiber anamandla aphezulu. Kodwa-ke, izifundo ezalandela zithole ukuthi ukukhishwa kwamandla aphezulu kulesi sakhiwo kulula ukuholela ekungazinzini kokusatshalaliswa kwendawo ngaphakathi kwe-fiber laser, futhi ukukhanya kwe-laser okuphumayo kuzothinteka ngezinga elithile, okuphinde kube nomthelela oqondile emphumeleni wokukhishwa kwamandla aphezulu.

Ngokuthuthuka kobuchwepheshe bokupompa

Ubude besikhathi sokupompa be-laser yefayibha yokuqala ye-ytterbium ngokuvamile buyi-915nm noma i-975nm, kodwa lawa ma-wavelength amabili okupompa ayiziqongo zokumunca zama-ion e-ytterbium, ngakho-ke kubizwa ngokuthi ukupompa okuqondile, ukupompa okuqondile akukaze kusetshenziswe kabanzi ngenxa yokulahleka kwe-quantum. Ubuchwepheshe bokupompa ngaphakathi kwebhendi buyisandiso sobuchwepheshe bokupompa okuqondile, lapho ubude besikhathi phakathi kobude besikhathi sokupompa kanye nobude besikhathi bokudlulisa bufana, futhi izinga lokulahlekelwa kwe-quantum lokupompa ngaphakathi kwebhendi lincane kunelokupompa okuqondile.

I-laser yefayibha enamandla aphezuluingqinamba yokuthuthukiswa kobuchwepheshe

Nakuba ama-fiber lasers enenani eliphezulu lokusetshenziswa kwezempi, ezokwelapha kanye nezinye izimboni, iShayina ikhuthaze ukusetshenziswa kabanzi kwama-fiber lasers eminyakeni ecishe ibe ngu-30 yocwaningo nentuthuko yobuchwepheshe, kodwa uma ufuna ukwenza ama-fiber lasers angakhipha amandla aphezulu, kusenezingqinamba eziningi kubuchwepheshe obukhona. Isibonelo, ukuthi amandla okukhipha e-fiber laser angafinyelela yini kumodi eyodwa ye-fiber single-mode engu-36.6KW; Ithonya lamandla okupompa emandleni okukhipha e-fiber laser; Ithonya lomphumela welensi yokushisa emandleni okukhipha e-fiber laser.

Ngaphezu kwalokho, ucwaningo lobuchwepheshe bokukhipha amandla aphezulu kwe-fiber laser kufanele lucabangele nokuzinza kwemodi eguquguqukayo kanye nomphumela wokufiphaza i-photon. Ngokucwaninga, kusobala ukuthi isici esithonyayo sokungazinzi kwemodi eguquguqukayo ukushisa kwefayibha, futhi umphumela wokufiphaza i-photon ubhekisela kakhulu ekutheni lapho i-fiber laser ikhipha amakhulu ama-watts noma ama-kilowatts amaningana wamandla, amandla okukhipha azobonisa ukuthambekela kokwehla okusheshayo, futhi kunezinga elithile lomkhawulo ekukhishweni kwamandla okuphezulu okuqhubekayo kwe-fiber laser.

Nakuba izimbangela ezithile zomphumela wokufiphala kwe-photon zingakachazwa ngokucacile okwamanje, abantu abaningi bakholelwa ukuthi isikhungo sokukhubazeka komoya-mpilo kanye nokumuncwa kokushaja kungaholela ekuveleni komphumela wokufiphala kwe-photon. Kulezi zici ezimbili, kuphakanyiswa izindlela ezilandelayo zokuvimbela umphumela wokufiphala kwe-photon. Njenge-aluminium, i-phosphorus, njll., ukuze kugwenywe ukumuncwa kokushaja, bese i-fiber esebenzayo elungiselelwe kahle ihlolwa futhi isetshenziswe, indinganiso ethile iwukugcina ukukhishwa kwamandla angu-3KW amahora amaningana nokugcina ukukhishwa okuzinzile kwamandla angu-1KW amahora ayi-100.
