1, oghere ìhè mgbapụta Ọdịdị
Laser eriri mbụ na-ejikarị mmepụta mgbapụta anya,lasermmepụta, ike mmepụta ya dị ala, iji mee ka ike mmepụta nke laser fiber dịkwuo ngwa ngwa n'ime oge dị mkpirikpi enwere ihe isi ike ka ukwuu.Na 1999, mmepụta ike nke fiber laser nnyocha na mmepe ubi mebiri 10,000 watts maka oge mbụ, Ọdịdị nke eriri laser bụ tumadi ojiji nke ngwa anya bidirectional pumping, na-akpụ a resonator, na nyocha nke mkpọda arụmọrụ nke eriri. Laser ruru 58.3%.
Otú ọ dị, ọ bụ ezie na iji eriri mgbapụta ọkụ na teknụzụ njikọ njikọ laser na-emepụta fiber lasers nwere ike imeziwanye ike mmepụta nke lasers fiber, ma n'otu oge ahụ enwere mgbagwoju anya, nke na-adịghị eme ka oghere anya anya iji wuo ụzọ ngwa anya. ozugbo laser kwesịrị ịkwaga n'ime usoro nke iwu ụzọ anya, mgbe ahụ, ụzọ anya ahụ dịkwa mkpa ka a gbanwee ya ọzọ, nke na-egbochi ngwa ngwa ngwa mgbapụta ngwa anya fiber lasers.
2, usoro oscillator ozugbo na usoro MOPA
Site na mmepe nke fiber lasers, cladding power strippers ejirila nke nta nke nta dochie ihe mejupụtara oghere oghere, na-eme ka usoro mmepe nke laser fiber dị mfe ma na-emeziwanye arụmọrụ nke laser fiber n'ụzọ na-edoghị anya.Usoro mmepe a na-egosipụta ngwa ngwa nke laser fiber.Ọdịdị oscillator Direct na usoro MOPA bụ ụlọ abụọ kachasị ewu ewu nke laser fiber na ahịa.Ọdịdị oscillator kpọmkwem bụ na grating na-ahọrọ ogologo ogologo ogologo n'ime usoro oscillation, wee wepụta ogologo wavelength ahọpụtara, ebe MOPA na-eji ogologo wavelength nke grating họọrọ dị ka ìhè mkpụrụ, na ìhè mkpụrụ na-amụba n'okpuru omume nke mbụ. -level amplifier, ya mere a ga-emeziwanye ike mmepụta nke laser fiber ruo n'ókè ụfọdụ.Ruo ogologo oge, a na-eji laser fiber nwere ihe owuwu MPOA mee ihe dị ka ihe kachasị amasị maka lasers fiber dị elu.Otú ọ dị, ọmụmụ ndị sochirinụ achọpụtala na mmepụta ike dị elu na nhazi a dị mfe iji mee ka enweghi ike nkesa oghere n'ime laser fiber, na nchapụta laser nke mmepụta ga-emetụta ruo n'ókè ụfọdụ, nke nwekwara mmetụta kpọmkwem. na mmetụta mmepụta ike dị elu.
Site na mmepe nke teknụzụ mgbapụta
Ogologo oge mgbapụta nke ytterbium-doped fiber laser nke mbụ na-abụkarị 915nm ma ọ bụ 975nm, mana ogologo ikuku abụọ a na-agbapụta bụ ọnụ ọgụgụ kachasị elu nke ytterbium ion, ya mere a na-akpọ ya mgbapụta ozugbo, a naghị eji mgbapụta ozugbo eme ihe n'ihi oke ọnwụ.Nkà na ụzụ na-agbapụta n'ime-band bụ ndọtị nke nkà na ụzụ na-agbapụta kpọmkwem, bụ nke ogologo nfe dị n'etiti mgbapụta mgbapụta na ikuku na-ebufe bụ nke yiri ya, na ọnụ ọgụgụ ọnwụ nke in-band dị ntakịrị karịa nke mgbapụta ozugbo.
Igwe ọkụ laser dị elumgbochi mmepe teknụzụ
Ọ bụ ezie na eriri lasers nwere elu ngwa uru na agha, ọgwụ na ndị ọzọ na ụlọ ọrụ, China akwalitewo mbara ngwa nke eriri lasers site fọrọ nke nta 30 afọ nke nkà na ụzụ nnyocha na mmepe, ma ọ bụrụ na ị chọrọ ime fiber lasers nwere ike mmepụta elu ike, a ka nwere. ọtụtụ ihe mgbochi na teknụzụ dị ugbu a.Ka ihe atụ, ma mmepụta ike nke eriri laser nwere ike iru otu-fiber single-mode 36.6KW;Mmetụta nke mgbapụta ike na fiber laser mmepụta ike;Mmetụta nke oghere oghere thermal na ike mmepụta nke laser fiber.
Na mgbakwunye, nyocha nke teknụzụ mmepụta ike dị elu nke laser fiber kwesịrị ịtụle nkwụsi ike nke ọnọdụ transverse na mmetụta ịgba ọchịchịrị photon.Site na nyocha, o doro anya na ihe mmetụta nke enweghị ntụkwasị obi nke transverse bụ eriri ọkụ, yana mmetụta photon na-agba ọchịchịrị na-ezo aka na mgbe laser fiber na-arụpụta ọtụtụ narị watts ma ọ bụ ọtụtụ kilowatts nke ike, ike mmepụta ga-egosi ngwa ngwa ọdịda na-emekarị, na e nwere ụfọdụ n'ókè nke mmachi na-aga n'ihu elu ike mmepụta nke eriri laser.
Ọ bụ ezie na akọwapụtabeghị nke ọma ihe ndị na-akpata mmetụta ịgba ọchịchịrị photon ugbu a, ọtụtụ ndị mmadụ kwenyere na etiti ntụpọ oxygen na nnabata nnyefe ụgwọ nwere ike iduga n'ọdịdị nke mmetụta ọchịchịrị photon.N'ihe abụọ a, a na-atụ aro ụzọ ndị a iji gbochie mmetụta ịgba ọchịchịrị photon.Dị ka aluminom, phosphorus, wdg, iji zere nnabata nnyefe ụgwọ, wee nwalee fiber na-arụ ọrụ kachasị mma ma tinye ya n'ọrụ, ọkọlọtọ akọwapụtara bụ idobe mmepụta ike 3KW ruo ọtụtụ awa ma nọgide na-arụ ọrụ ike 1KW maka awa 100.
