Hamwe niterambere rihoraho rya siyanse nikoranabuhanga no kwagura ibikorwa bitandukanye,lasertekinoroji yo gutunganya igenda yinjira mubice byose kandi igahinduka igikoresho cyingenzi cyo gutunganya. Mu ikoreshwa rya laseri,kilowatt-urwego MOPA(Master Oscillator Power-Amplifier) lazeri ikoreshwa cyane mubice nko gutunganya ibikoresho hamwe nubushakashatsi bwubushakashatsi bwa siyansi bitewe nimbaraga zabo zo hejuru, kwinjira cyane, hamwe nubushyuhe buke. Nibikoresho byingenzi bifasha ibigo kuzamura ireme no kongera umusaruro. Igikoresho cyiza cyo gukora neza. Ariko mubyukuri kubera imbaraga zayo nyinshi, kugirango twongere uburyo bwo gutunganya imikorere ya kilowatt yo murwego rwa MOPA laser, guhitamo ibikoresho nibyingenzi. Gusa muguhitamo ibikoresho bya lazeri bikwiye turashobora kwemeza ko laser ishobora gukora neza kandi neza kandi neza kandi igahuza ibyifuzo bitandukanye.
Imbaraga zikomeye
Umusaruro mwinshi wa kilowatt-urwego MOPA hamwe nibikorwa byinshi nibipimo bya tekiniki
Ubushobozi bwo gutanga umusaruro-mwinshikilowatt-urwego rumwe-moderi ya MOPAni ikimenyetso cyingenzi cyerekana sosiyete MOPA laser R&D, umusaruro nubushobozi bwo gukora. MAVEN kuri ubu ifite verisiyo nyinshi zingufu za MOPA fibre laser yoza ibikoresho bishobora gutunganya ibikenerwa bitandukanye muburyo butandukanye.
24h yuzuye imbaraga zisohoka zihindagurika ni munsi ya <3%
Igiti cyiza gishobora kugenzurwa
Uburyo bumwe bwa Gaussian beam Ubwoko bwinshi-buringaniye-hejuru
Ikoreshwa rya tekinoroji ya nyuma ya pompe, uburyo bunoze kandi bunoze bwo gukwirakwiza ingufu, uburyo budasanzwe bwo gutondekanya ibicuruzwa, hamwe nuburyo bumwe bwo hejuru-imbaraga-zegeranijwe hamwe na kristu nziza cyane, mugihe ingufu zisohoka zigera kuri 1000W, birashobora kandi kwemeza ubwiza bwa Beam.
Mu rwego rwo gutunganya fibre laser, cyane cyane gutunganyaimbaraga nyinshi MOPA nanosekond pulse fibre laser, kubera imbaraga zayo zo hejuru, ingufu nini za pulse ninshuro nyinshi, guhitamo ibikoresho nibyingenzi. Ibikoresho byingenzi bigira ingaruka kumikorere ya laser-power-pulse laser harimo Scanning galvanometer, yibanda kumirorerwamo yumurima na ecran.
Nigute ushobora guhitamo scanning galvanometero?
Intego ya tekinoroji ya galvanometero ni ukurangiza imirimo yihuta, yuzuye-yogusuzuma. Hariho ibintu bibiri by'ingenzi bigena. Imwe ni sisitemu yo kugenzura ishobora kugera ku muvuduko mwinshi kandi neza, naho indi ni galvanometero ifite umuvuduko wo gusubiza byihuse. scaneri. Imiterere ya galvanometero igizwe ahanini nibice bitatu: ibyuma byerekana, moteri na karita yo gutwara, muri byo lens ni ingenzi cyane mugutunganya gutunganya.
Galvanometero yerekana ibikoresho nibipimo byerekana
Sisitemu yo gucunga ubushyuhe bwagusikana galvanometeroni nacyo kintu cyingenzi mugukomeza gutunganya igihe kirekire. Itandukaniro ryubushyuhe rizatera galvanometero gutembera no kugabanya imyanya ihagaze. Indangagaciro zisanzwe nizi zikurikira. Binyuze mu gukonjesha amazi gukwirakwiza ubushyuhe, gutunganya igihe kirekire birashobora gutezimbere 30%.
Ubushyuhe busanzwe butwara agaciro ka galvanometero
Igikoresho gikonjesha amazi kirashobora gukuraho neza ubushyuhe no kwemeza imikorere yigihe kirekire ya galvanometero. Uburyo bukuru bwa tekiniki ni ukubona umurima muke wamazi ukonje ukoresheje igishushanyo mbonera cyumuyoboro wogukonjesha, no gushushanya uburyo bwiza bwo guhanahana ubushyuhe hanze.
Muri kilowatt yo murwego rwohejuru-MOPA pulse laser sisitemu, turasaba cyane ko hakoreshwa lens nziza ya quartz nziza na sisitemu ya galvanometero hamwe na sisitemu yo gukonjesha amazi.
Nigute ushobora guhitamo intumbero yibanze?
Lens yumurima yibanda kumurongo wa lazeri yegeranijwe kumurongo, yongerera ingufu ingufu za lazeri, kandi ikoresha ingufu nyinshi za lazeri kugirango ikore ibintu bitandukanye nko gukata, gushiraho ikimenyetso, gusudira, gusukura no kuvura hejuru.
Ibintu nyamukuru bigira ingaruka kumikorere yatunganijwe ningaruka zumurima wumurima ni ibikoresho byumurongo wumurima hamwe nuburebure bwimpeta ya adapt. Ibikoresho nyamukuru byumurima ni ibirahuri na quartz. Itandukaniro riri hagati yibi byombi rifite ingufu za lens yumuriro ku mbaraga nyinshi. Nyuma yo kwibanda kumurongo wibibanza bikomeza kumurikirwa nurumuri rwa lazeri igihe kirekire, bizatanga impinduka zumuriro bitewe nubwiyongere bwubushyuhe, buzatera optique. Indangantego yo kuvunika yibintu hamwe nicyerekezo cyo kwerekana icyerekezo cya optique ihinduka, hamwe nubushyuhe bwa lens yumuriro bizagira ingaruka kumiterere ya laser hamwe numwanya wibanze nyuma yo kwibanda, bizagira ingaruka zikomeye kubikorwa byo gutunganya. Quartz ifite coefficente yo kwagura ubushyuhe buke hamwe nogukwirakwiza kwinshi, bigatuma ihitamo ibintu byiza kumashanyarazi menshi. Nibiba ngombwa, module ikonjesha amazi igomba kongerwamo.
Impeta ya adapt yo guhuza lens yumurima na galvanometero nayo ni ikintu cyingenzi kigira ingaruka kubikoresho no kubitunganya. Uburebure bukwiye bwimpeta ya adapt burashobora kwirinda kugaruka kumwanya wumurima no kwemeza uburyo bwo gutunganya. Niba ari hejuru cyane cyangwa hasi cyane, bizatera ibibazo bijyanye.
Muri kilowatt-urwego rwohejuru-MOPA pulse laser sisitemu, turasaba cyane ko hakoreshwa indorerwamo nziza ya quartz yumurima hamwe na moderi ikonjesha amazi hamwe nindorerwamo yabugenewe indorerwamo ya adapt yuburebure bukwiye.
Nigute ushobora guhuza utuntu twerekana?
Igikorwa nyamukuru cyinzira zigaragaza muburyo bwa optique yinzira ni uguhindura icyerekezo cyinzira nziza. Guhitamo ubuziranenge bwiza bwerekana uburyo hamwe nuburyo busanzwe bwo kwishyiriraho burashobora kugira uruhare runini mubikorwa bimwe bidasanzwe, ariko ubuziranenge bwuburyo bwiza hamwe nuburyo bwo kwishyiriraho bidafite ishingiro nabyo bizatera ikibazo gishya. Ibintu biranga lens bigenwa nuburebure bwimbaraga nimbaraga za laser. Ubusanzwe substrate ikozwe muri quartz yahujwe cyangwa silicon. Filime yerekana laser muri rusange ikozwe muri firime ya feza cyangwa firime ya dielectric ya mucyo, ifite imbaraga nyinshi, igabanuka ryinshi hamwe na laser. Ibiranga ibyangiritse cyane.
Icyerekezo cyiza cyindege ntikizagira ingaruka kumiterere yibanze, ariko mugukoresha nyacyo, indege yerekana irashobora guhinduka kubera ibintu bitera impagarara nko gukosora imigozi, bisa nindorerwamo ya silindrike. Kugoreka bigira ingaruka cyane cyane kumiterere yibibanza, bitera astigmatism yo murwego rwo hasi hamwe nizindi astigmatism yo murwego rwo hasi. Aberration ibuza umwanya wibanze kugera kumipaka yo gutandukanya, bigira ingaruka kumikorere n'ingaruka.
Muri kilowatt-urwego rwohejuru rwa MOPA pulse laser sisitemu, turasaba cyane ko hakoreshwa ibyuma byerekana ibyuma bya quartz byujuje ubuziranenge hamwe nuburyo bukwiye bwo kwishyiriraho kugirango tumenye neza ko lens zifite imbaraga zidahinduka.
