Ubuchwepheshe be-fibre buthuthukisa amandla nokukhanya kwe-blue semiconductor laser

Ubuchwepheshe be-fiber buthuthukisa amandla nokukhanya kwe-i-laser ye-semiconductor eluhlaza okwesibhakabhaka

Ukubumba imisebe kusetshenziswa ubude besikhathi obufanayo noma obuseduzei-laserIyunithi iyisisekelo sokuhlanganiswa kwemisebe eminingi ye-laser yamaza ahlukahlukene. Phakathi kwazo, ukubopha imisebe yendawo kuwukufaka imisebe eminingi ye-laser esikhaleni ukuze kwandiswe amandla, kodwa kungabangela ukuthi ikhwalithi yomsebe yehle. Ngokusebenzisa isici se-linear polarization se-i-laser ye-semiconductor, amandla emishayo emibili okuqondiswa kwayo ukudlidliza kuqondile komunye nomunye ingandiswa cishe kabili, kuyilapho ikhwalithi yemishayo ingashintshi. I-Fiber bundler iyidivayisi ye-fiber elungiselelwe ngokusekelwe ku-Taper Fused Fiber Bundle (TFB). Iwukukhumula inqwaba yengqimba yokumboza i-optical fiber, bese ihlelwa ndawonye ngendlela ethile, ifudunyezwe ekushiseni okuphezulu ukuze incibilikiswe, ngenkathi ilula inqwaba ye-optical fiber ngakolunye uhlangothi, indawo yokushisa ye-optical fiber iyancibilika ibe yi-fused cone optical fiber bundle. Ngemva kokunquma okhalweni lwe-cone, hlanganisa ukuphela kokukhipha kwe-cone ne-output fiber. Ubuchwepheshe be-fibre bunching bungahlanganisa ama-fibre bundle amaningi abe yi-bundle enobubanzi obukhulu, ngaleyo ndlela kufezwe ukudluliselwa kwamandla aphezulu kwe-optical. Isibalo 1 yi-schematic diagram yei-laser eluhlaza okwesibhakabhakaubuchwepheshe befayibha.

Indlela yokuhlanganisa imisebe ye-spectral isebenzisa isici esisodwa sokuhlakaza i-chip ukuze ihlanganise imisebe eminingi ye-laser ngesikhathi esisodwa ngezikhawu zobude be-wavelength eziphansi njenge-0.1 nm. Imisebe eminingi ye-laser yama-wavelength ahlukene iyenzeka ku-element dispersive engela ezahlukene, idlulele ku-element, bese i-diffract bese ikhipha ohlangothini olufanayo ngaphansi kwesenzo sokuhlakazeka, ukuze i-laser beam ehlanganisiwe idlulele komunye nomunye ensimini eseduze nasensimini ekude, amandla alingana nesamba semisebe yeyunithi, futhi ikhwalithi yemisebe iyahambisana. Ukuze kufezwe inhlanganisela ye-spectral beam enesikhala esincane, i-diffraction grating ene-dispersion enamandla ivame ukusetshenziswa njengesici sokuhlanganiswa kwemisebe, noma i-surface grating ehlanganiswe nemodi yempendulo yesibuko sangaphandle, ngaphandle kokulawula okuzimele kwe-spectrum yeyunithi ye-laser, kunciphisa ubunzima nezindleko.

I-laser eluhlaza okwesibhakabhaka kanye nomthombo wayo wokukhanya ohlanganisiwe one-laser ye-infrared kusetshenziswa kabanzi emkhakheni wokushisela insimbi engena-ferrous kanye nokukhiqizwa kwezengezo, kuthuthukiswa ukusebenza kahle kokuguqulwa kwamandla kanye nokuqina kwenqubo yokukhiqiza. Izinga lokumuncwa kwe-laser eluhlaza okwesibhakabhaka kwezinsimbi ezingena-ferrous likhuliswa izikhathi eziningana kuya ezikhathini eziyishumi kune-laser ye-wavelength eseduze ne-infrared, futhi liphinde lithuthukise i-titanium, i-nickel, insimbi kanye nezinye izinsimbi ngezinga elithile. Ama-laser aluhlaza okwesibhakabhaka anamandla aphezulu azohola ukuguqulwa kokukhiqizwa kwe-laser, futhi ukuthuthukisa ukukhanya nokunciphisa izindleko kuyinkambiso yentuthuko yesikhathi esizayo. Ukukhiqizwa kwezengezo, ukumbozwa kanye nokushiselwa kwezinsimbi ezingena-ferrous kuzosetshenziswa kabanzi.

Esigabeni sokukhanya okuphansi okuluhlaza okwesibhakabhaka kanye nezindleko eziphezulu, umthombo wokukhanya ohlanganisiwe we-laser eluhlaza okwesibhakabhaka kanye ne-laser eseduze kwe-infrared ungathuthukisa kakhulu ukusebenza kahle kokuguqulwa kwamandla kwemithombo yokukhanya ekhona kanye nokuzinza kwenqubo yokukhiqiza ngaphansi kwesisekelo sezindleko ezingalawuleki. Kubaluleke kakhulu ukuthuthukisa ubuchwepheshe obuhlanganisa imisebe ye-spectrum, ukuxazulula izinkinga zobunjiniyela, kanye nokuhlanganisa ubuchwepheshe beyunithi ye-laser yokukhanya okuphezulu ukuze kufezwe umthombo we-laser we-semiconductor eluhlaza okwesibhakabhaka okhanyayo kakhulu we-kilowatt, kanye nokuhlola ubuchwepheshe obusha bokuhlanganisa imisebe. Ngokwanda kwamandla e-laser nokukhanya, kungakhathaliseki ukuthi kungumthombo wokukhanya oqondile noma ongaqondile, i-laser eluhlaza okwesibhakabhaka izoba yinto ebalulekile emkhakheni wezokuvikela kazwelonke kanye nemboni.
