Ukuziphendukela kwemvelo kwamandla aphezulu ama-laser fiber

Ukuthuthukisa kwei-fiber laserisakhiwo

1, isakhiwo iphampu ukukhanya isikhala

Ama-laser e-fiber okuqala ayesebenzisa ukuphuma kwepompo ye-optical,laserokukhiphayo, amandla ayo okukhiphayo aphansi, ukuze kuthuthukiswe ngokushesha amandla okukhipha ama-fiber lasers ngesikhathi esifushane kunobunzima obukhulu. Ngo-1999, amandla okukhipha ocwaningo lwe-fiber laser kanye nomkhakha wokuthuthukiswa aphuka ama-watts angu-10,000 okokuqala ngqa, ukwakheka kwe-fiber laser ngokuyinhloko kusetshenziselwa ukupompa kwe-optical bidirectional, ukwakha i-resonator, ngophenyo lokusebenza kahle komthambeka we-fiber. i-laser ifinyelele ku-58.3%.
Kodwa-ke, nakuba ukusetshenziswa kwe-fiber pump light kanye nobuchwepheshe bokuhlanganisa i-laser ukuthuthukisa i-fiber lasers kungathuthukisa ngempumelelo amandla okukhipha ama-fiber lasers, kodwa ngesikhathi esifanayo kuyinkimbinkimbi, engahambisani ne-lens optical ukwakha indlela yokubona, uma i-laser idinga ukuhanjiswa ohlelweni lokwakha indlela yokubona, khona-ke indlela ye-optical nayo idinga ukulungiswa kabusha, okukhawulela ukusetshenziswa okubanzi kwe-optical pump structure fibre lasers.

2, ukwakheka okuqondile kwe-oscillator kanye nesakhiwo se-MOPA

Ngokuthuthukiswa kwama-laser e-fiber, ama-cladding power strippers kancane kancane athathe indawo yezingxenye zamalensi, enza lula izinyathelo zokuthuthukiswa kwama-fiber lasers futhi athuthukise ngokungaqondile ukusebenza kahle kokugcinwa kwe-fiber lasers. Lo mkhuba wokuthuthuka ufanekisela ukusebenza kancane kancane kwama-fiber lasers. Isakhiwo se-oscillator esiqondile kanye nesakhiwo se-MOPA yizakhiwo ezimbili ezivame kakhulu zama-fiber lasers emakethe. Isakhiwo se-oscillator esiqondile siwukuthi igridi ikhetha ubude beza ngenqubo ye-oscillation, bese ikhipha ubude begagasi obukhethiwe, kuyilapho i-MOPA isebenzisa ubude begagasi obukhethwe igriza njengokukhanya kwembewu, futhi ukukhanya kwembewu kuyakhuliswa ngaphansi kwesenzo sokuqala. -i-amplifier yezinga, ngakho-ke amandla okukhipha i-fiber laser nawo azothuthukiswa ngezinga elithile. Isikhathi eside, i-fiber lasers enesakhiwo se-MPOA isetshenziswe njengesakhiwo esithandwayo sama-laser we-fiber enamandla aphezulu. Kodwa-ke, izifundo ezalandela zithole ukuthi ukuphuma kwamandla aphezulu kulesi sakhiwo kulula ukuholela ekungazinzini kokusatshalaliswa kwendawo ngaphakathi kwe-fiber laser, futhi ukukhanya kwe-laser okukhiphayo kuzothinteka ngezinga elithile, elibuye libe nomthelela oqondile. kumphumela wokukhipha amandla aphezulu.

Ngokuthuthukiswa kobuchwepheshe bokudonsa

Ubude begagasi obumpompayo be-laser ye-fiber ye-ytterbium-doped yakuqala ngokuvamile bungu-915nm noma u-975nm, kodwa lawa maza amaza okupompa amabili ayiziqongo zokumuncwa zama-ion e-ytterbium, ngakho kubizwa ngokuthi ukupompa okuqondile, ukumpompa okuqondile akukaze kusetshenziswe kabanzi ngenxa yokulahleka kwe-quantum. Ubuchwepheshe bokumpompa okungaphakathi kwebhendi buyisandiso sobuchwepheshe bokumpompa okuqondile, lapho ubude begagasi phakathi kwe-wavelength yokumpompa kanye ne-wavelength yokudlulisela bufana, futhi izinga lokulahlekelwa kwe-quantum lokumpompa okungaphakathi kwebhendi lincane kunelo lokumpompa okuqondile.

Amandla aphezulu we-fiber laseribhodlela lokuthuthukiswa kobuchwepheshe

Nakuba i-fiber lasers inenani eliphakeme lokufaka isicelo kwezempi, ezokwelapha nakwezinye izimboni, i-China ikhuthaze ukusetshenziswa okubanzi kwe-fiber lasers cishe iminyaka engu-30 yocwaningo nokuthuthukiswa kobuchwepheshe, kodwa uma ufuna ukwenza i-fiber lasers ingakhipha amandla aphezulu, zisekhona izingqinamba eziningi kubuchwepheshe obukhona. Isibonelo, ukuthi amandla okukhiphayo we-fibre laser angafinyelela kumodi eyodwa yefiber engu-36.6KW; Umthelela wamandla okupompa emandleni okukhipha i-fiber laser; Umthelela womphumela welensi eshisayo emandleni okukhipha e-fiber laser.

Ngaphezu kwalokho, ucwaningo lobuchwepheshe obuphezulu bokukhipha amandla e-fiber laser kufanele futhi lucabangele ukuzinza kwemodi eguquguqukayo kanye nomphumela wokuba mnyama kwe-photon. Ngophenyo, kuyacaca ukuthi into enomthelela wokungazinzi kwemodi eguquguqukayo ukushisisa ifayibha, futhi umphumela wokuba mnyama kwe-photon ubhekisela ikakhulukazi kulokho lapho i-fiber laser ngokuqhubekayo ikhipha amakhulukhulu wama-watts noma ama-kilowatts ambalwa wamandla, amandla okukhiphayo azobonisa ukuthambekela kokwehla ngokushesha, futhi kunezinga elithile lomkhawulo ekuphumeni kwamandla aphezulu okuqhubekayo kwe-fiber laser.

Nakuba izimbangela ezithile zomphumela we-photon mnyama zingakachazwa ngokucacile okwamanje, abantu abaningi bakholelwa ukuthi isikhungo se-oxygen defect kanye nokumuncwa kokudlulisa ukushaja kungaholela ekuveleni komphumela wokuba mnyama kwe-photon. Kulezi zici ezimbili, kuhlongozwa izindlela ezilandelayo ukuze kuvinjwe umphumela wokuba mnyama kwe-photon. Okufana ne-aluminium, i-phosphorus, njll., ukuze ugweme ukumuncwa ukudluliswa kwenkokhiso, bese kuthi ifayibha esebenzayo elungiselelwe ihlolwe futhi isetshenziswe, izinga elithile ukugcina ukuphuma kwamandla angu-3KW amahora ambalwa nokugcina ukuphuma kwamandla okuzinzile okungu-1KW amahora angu-100.
