Iterambere rya tekiniki rya lasers zifite imbaraga nyinshi

Kunoza imikorere yalaser ya fibreimiterere

1, imiterere y'ipompo y'urumuri rw'ikirere

Laser za kera za fibre zakoreshaga cyane cyane pompe y'amashanyarazi,laserUmusaruro wayo, imbaraga zayo zo gusohora ni nke, kugira ngo wongere vuba imbaraga zo gusohora za fibre laser mu gihe gito, hari ingorane nyinshi. Mu 1999, imbaraga zo gusohora za fibre laser zagabanutseho watts 10.000 ku nshuro ya mbere, imiterere ya fibre laser ahanini ikoreshwa mu gupompa impande ebyiri, ikora resonator, aho iperereza ku miterere y’imirongo ya fibre laser ryageze kuri 58.3%.
Ariko, nubwo gukoresha ikoranabuhanga rya fibre pump n'ikoranabuhanga ryo guhuza fibre laser mu guteza imbere fibre laser bishobora kunoza neza imbaraga zo gusohora fibre laser, ariko icyarimwe hari ingorane, zidafasha lens optique kubaka inzira y'urumuri, iyo laser ikeneye kwimurwa mu gihe cyo kubaka inzira y'urumuri, inzira y'urumuri nayo igomba guhindurwa, ibyo bikaba bigabanya ikoreshwa rya fibre lasers optique structure.

2, imiterere ya oscillator itaziguye n'imiterere ya MOPA

Bitewe n’iterambere rya fibre lasers, cladding power strippers zagiye zisimbura buhoro buhoro ibice by’indorerwamo, byoroshya intambwe zo guteza imbere fibre lasers no kunoza uburyo butaziguye imikorere ya fibre lasers. Iyi nzira y’iterambere igaragaza uburyo fibre lasers zikora buhoro buhoro. Imiterere ya oscillator ikoresha direct oscillator n’imiterere ya MOPA ni byo bintu bibiri bikunze gukoreshwa cyane muri fibre lasers ku isoko. Imiterere ya oscillator ikoresha direct oscillator ni uko grating ihitamo uburebure bw’umurambararo mu gihe cyo guhindagurika, hanyuma igasohora uburebure bw’umurambararo bwatoranijwe, mu gihe MOPA ikoresha uburebure bw’umurambararo bwatoranijwe na grating nk’urumuri rw’imbuto, maze urumuri rw’imbuto rwongerwa bitewe n’igikorwa cya amplifier yo ku rwego rwa mbere, bityo imbaraga zo gutanga za fibre laser nazo zizarushaho kunozwa ku rugero runaka. Mu gihe kirekire, fibre lasers zifite imiterere ya MPOA zakoreshejwe nk’imiterere ikunzwe cyane kuri fibre lasers zifite imbaraga nyinshi. Ariko, ubushakashatsi bwakurikiyeho bwagaragaje ko umusaruro mwinshi w’ingufu muri ubu buryo byoroshye gutuma ikwirakwizwa ry’ahantu muri fibre laser ritagenda neza, kandi urumuri rwa laser rusohoka ruzagira ingaruka ku rugero runaka, ibyo bikaba bigira ingaruka zitaziguye ku ngaruka z’umusaruro mwinshi.

Hamwe n'iterambere ry'ikoranabuhanga ryo kuvoma

Ubunini bw'umurambararo wa laser ya fibre ya ytterbium ikoreshwa mu gupima ubunini bw'umurambararo akenshi ni 915nm cyangwa 975nm, ariko ubu burebure bubiri bwo gupima ni bwo bunini bw'ingufu za ytterbium, bityo byitwa gupima ubunini bw'umurambararo, gupima ubunini bw'umurambararo ntibwakoreshejwe cyane kubera igihombo cya quantum. Ikoranabuhanga ryo gupima ubunini bw'umurambararo ni uburyo bwo kongera ikoranabuhanga ryo gupima ubunini bw'umurambararo, aho ubunini bw'umurambararo buri hagati y'ubunini bw'umurambararo bwo gupima ubunini bw'umurambararo n'ubunini bw'umurambararo bwo kohereza bungana, kandi igipimo cyo gutakaza ubunini bw'umurambararo bwo gupima ubunini bw'umurambararo ni gito ugereranyije n'ubunini bw'umurambararo bwo gupima ubunini bw'umurambararo.

Laser ifite imbaraga nyinshiimbogamizi mu iterambere ry'ikoranabuhanga

Nubwo fiber laser zifite agaciro kanini mu nganda za gisirikare, ubuvuzi n'izindi, Ubushinwa bwateje imbere ikoreshwa rya fiber laser mu myaka hafi 30 y'ubushakashatsi n'iterambere ry'ikoranabuhanga, ariko niba ushaka gukora fiber laser zishobora gutanga imbaraga nyinshi, haracyari ibibazo byinshi mu ikoranabuhanga ririho. Urugero, niba imbaraga zo gusohora za fiber laser zishobora kugera kuri single-fiber single-mode 36.6KW; Ingaruka z'ingufu zo gusohora kuri fiber laser; Ingaruka z'ingaruka z'ubushyuhe ku mbaraga zo gusohora za fiber laser.

Byongeye kandi, ubushakashatsi ku ikoranabuhanga ryo gutanga ingufu nyinshi rya fiber laser bugomba kandi gusuzuma uburyo bwo guhagarara kw'uburyo bunyuranamo n'ingaruka zo kwijima kwa photon. Binyuze mu bushakashatsi, biragaragara ko ingaruka z'uburyo bunyuranamo ari ugushyushya fibre, kandi ingaruka zo kwijima kwa photon yerekeza ahanini ku kuba iyo fiber laser ikomeza gutanga watts amagana cyangwa kilowatts nyinshi z'ingufu, ingufu zisohoka zigaragaza icyerekezo cyo kugabanuka vuba, kandi hari urwego runaka rw'imbogamizi ku mbaraga zihoraho za fiber laser.

Nubwo impamvu zihariye zitera umwijima wa fotoni zitarasobanuka neza muri iki gihe, abantu benshi bizera ko imiterere y’umwuka wa ogisijeni n’uburyo bwo kohereza charge bishobora gutuma habaho umwijima wa fotoni. Kuri izi mpamvu ebyiri, hari uburyo bukurikira butangwa bwo gukumira umwijima wa fotoni. Nka aluminiyumu, fosifore, nibindi, kugira ngo hirindwe ubwiyongere bw’umuriro, hanyuma fibre ikora neza igapimwa igakoreshwa, igipimo cyihariye ni ugukomeza gutanga ingufu za 3KW mu gihe cy’amasaha menshi no kugumana ingufu za 1KW mu gihe cy’amasaha 100.
