Ukuvela kwezobuchwepheshe kwamandla aphezulu we-fiber lasers

Ukwenziwa kwe-i-fiber laserukwakheka

1, isakhiwo sepompo esikhanyayo esikhaleni

Ama-lesters asekuqaleni asetshenziswa kakhulu ukuphuma kwepompo optical pump,i-laserUkukhishwa, amandla ayo okukhipha aphansi, ukuze uthuthukise ngokushesha amandla okukhipha ama-fiber lasers ngesikhathi esifushane kunobunzima obufushane kunobunzima obufushane. Ngo-1999, amandla okukhipha e-Fibre Laser Research and Development Field aphule okokuqala, ukwakheka kwe-ler ye-fiber ikakhulukazi ukusetshenziswa kwe-slopealing ye-laser ye-fiber kufinyelele ku-58.3%.
Kodwa-ke, yize ukusetshenziswa kwe-Fiber Pump Light and Laser coupling Technology ukuthuthukisa ama-fiber lasers kungathuthukisa ngempumelelo amandla okukhipha ama-fiber lasers, kepha ngasikhathi sinye kudinga ukulungiswa kabusha, okudinga ukusetshenziswa okubanzi kwe-fiber tampu ye-fiber.

2, isakhiwo esiqondile se-oscillator nesakhiwo se-mopa

Ngokuthuthukiswa kwe-fiber lasers, ama-cloradding amandla amakhulu athathe indawo kancane kancane izingxenye zelensi, ukwenza lula izinyathelo zokuthuthuka ze-fiber lasers kanye nokwenza ngcono ukusebenza kahle kwe-fiber lasers. Lo mkhuba wentuthuko ufanekisela ukusebenza kancane kancane kwe-fiber lasers. Ukwakheka kwe-Oscillator eqondile nesakhiwo se-mopa yizinhlaka ezimbili ezivame kakhulu ze-fiber lasers emakethe. Isakhiwo se-Oscillator esiqondile ukuthi i-grating ikhetha i-wavelength enqubweni ye-oscillation, bese ikhipha i-wavelength ekhethiwe, futhi ukukhanya kwembewu kukhuliswe ngaphansi kwesenzo se-amplifier yokuqala, ngakho-ke amandla okukhipha we-fiber laser nawo azothuthukiswa ngezinga elithile. Isikhathi eside, ama-fiber lasers anesakhiwo se-MPOA asetshenzisiwe njengesakhiwo esithandwayo sama-lesters aphezulu we-fiber lasers. Kodwa-ke, izifundo ezilandelayo zithole ukuthi umphumela wamandla we-High

Ngokuthuthukiswa kobuchwepheshe bokupompa

I-wavelength yokuphonsa ye-ytterbium-doped fiber laser imvamisa imvamisa i-915NM noma i-975nm, kepha lezi zigaxekile ezimbili zokupompa ziyiziqongo zokutholwa kwama-ytterbium ion, ngakho-ke ibizwa ngokuthi ukumpompela i-ytterbium ion, ngakho-ke ibizwa ngokuthi yi-Direct Pumps, ukupompa okuqondile akukaze kusetshenziswe kabanzi ngenxa yokulahleka kwe-quantum. Ubuchwepheshe bePumpeling Band yisandiso sobuchwepheshe obuqondile bokumpompa, lapho i-wavelength phakathi kwe-wavength yokuphanga okufanayo, futhi isilinganiso sokulahleka kwe-quatum se-band mpompeng sincane kunalokho okuphampu okuqondile.

I-Hig Power Foib ye-LaserI-Technology Development Bottleneck

Yize ama-lasers e-fiber anenani eliphakeme lesicelo empini, ezokwelapha kanye nezinye izimboni, iChina ikhuthaze ukusetshenziswa okubanzi kwama-laser we-fiber cishe ngonyaka wama-30 ocwaningweni lwezobuchwepheshe kanye nokuthuthukiswa kwe-fiber yocwaningo lwezobuchwepheshe kanye nokuthuthukiswa kobuchwepheshe obusemabhodleleni akhona. Isibonelo, noma ngabe amandla okukhipha we-fiber laser angafinyelela kwimodi eyodwa ye-fiber eyodwa 36.6kw; Ithonya lamandla okupompa kumandla okukhishwa kwe-fiber laser; Ithonya lomphumela we-lens we-themal emandleni okukhipha we-fiber laser.

Ngaphezu kwalokho, ucwaningo lobuchwepheshe bokukhipha amandla aphezulu be-fiber laser kufanele futhi babheke nokuqina kwemodi yokuguquguquka kanye nomphumela we-Photon Ngokuphashelwa, kuyacaca ukuthi ingcebo yethonya yokungazinzi kwe-Transverse ukufudumala kwe-fiber, futhi amandla okuphuma akhombisa ukuqhubeka kwamakhulu lapho kuvela umkhawulo oqhubekayo wokukhishwa kwamandla okuqhubekayo kwe-fiber laser.

Yize izimbangela ezithile ze-Photon Darkning Effect azange zichazwe kahle njengamanje, iningi labantu likholelwa ukuthi i-O Oksijini Isici kanye nokukhishwa kokudluliswa kokudluliswa kungaholela ekutheni kube nokuvela komphumela we-Photon Carkning. Kulezi zinto ezimbili, izindlela ezilandelayo zihlongozwa ukuvimbela umphumela we-Photon Njengo-Aluminium, phosphorus, njll.
