Bitewe n'iterambere rihoraho rya siyansi n'ikoranabuhanga no kwaguka kw'amashami atandukanye akoreshwa,laserIkoranabuhanga ryo gutunganya ibintu rigenda ryinjira buhoro buhoro mu nzego zose z'ubuzima kandi rihinduka igikoresho cy'ingenzi cyo gutunganya ibintu. Mu ikoreshwa rya laser,MOPA yo ku rwego rwa kilowatiLazeri (Master Oscillator Power-Amplifier) zikoreshwa cyane mu nzego nko gutunganya ibikoresho no kugerageza ubushakashatsi bwa siyansi bitewe n'imbaraga zazo nyinshi, kwinjira cyane, n'ubushyuhe buke. Ni igikoresho cy'ingenzi cyo gufasha ibigo kunoza ireme no kongera umusaruro. Ni igikoresho cyiza cyo gukora neza. Ariko kubera imbaraga zacyo nyinshi, kugira ngo twongere imikorere myiza ya lazeri MOPA yo ku rwego rwa kilowatt, guhitamo ibikoresho ni ingenzi cyane. Guhitamo ibikoresho bikwiye ni byo byonyine bishobora gutuma lazeri ikora neza kandi neza kandi igahura neza n'ibikenewe mu buryo butandukanye.
Ingufu nyinshi zihamye
Umusaruro munini wa MOPA ku rwego rwa kilowati ifite imikorere myiza n'ibipimo bya tekiniki
Ubushobozi bwo gukora byinshi mu buryo buhorahokilowatt-urwego rumwe-moderi ya MOPAni ikimenyetso cy'ingenzi cy'ubushakashatsi n'iterambere bya MOPA laser, umusaruro n'ubushobozi bwo gukora. MAVEN ubu ifite verisiyo nyinshi z'imashini zo gusukura fibre laser za MOPA zifite imbaraga nyinshi zishobora guhaza ibyifuzo byo gutunganya ibikoresho bitandukanye mu buryo butandukanye.
Ihindagurika ry'ingufu zose risohoka mu masaha 24 riri munsi ya <3%
Ireme ry'umurabyo rigenzurwa
Umurabyo wa Gaussian wo mu buryo bumwe Umurabyo wo hejuru ugororotse w'uburyo bwinshi
Ikoranabuhanga ryo guhuza ibimenyetso bya pompe, gukwirakwiza ingufu neza kandi mu buryo bunoze, uburyo bwihariye bwo gukora coiling, hamwe na collimated isolateur ifite imbaraga nyinshi ifite kristale nziza cyane ibonerana mu bushyuhe, mu gihe ingufu zisohoka zigera kuri 1000W, ishobora kandi kwemeza ko Beam ari nziza cyane.
Mu rwego rwo gutunganya fibre laser, cyane cyane gutunganyalaser ya MOPA nanosecond pulse fiber ikoresha imbaraga nyinshi, bitewe n'imbaraga zayo zo hejuru, ingufu nyinshi zo gutera kw'amajwi n'umuvuduko mwinshi, guhitamo ibikoresho ni ingenzi cyane. Ibikoresho by'ingenzi bigira ingaruka ku ngaruka zo gutunganya laser ya pulse ifite imbaraga nyinshi birimo Scanning galvanometer, focusing field mirror na reflector.
Ni gute wahitamo galvanometer yo gupima?
Intego y'ikoranabuhanga ryo gupima galvanometer ni ugukora imirimo yo gupima yihuta cyane kandi neza. Hari ibintu bibiri by'ingenzi bigena. Kimwe ni uburyo bwo kugenzura bushobora kugera ku muvuduko mwinshi no ku buhanga bwinshi, ikindi ni galvanometer ifite umuvuduko wo gusubiza vuba. Imiterere ya galvanometer igizwe ahanini n'ibice bitatu: reflector, moteri na drive card, muri byo lens ni ingenzi cyane kugira ngo itunganywe neza.
Ibikoresho bya lenzi ya Galvanometer n'ibipimo by'ingaruka
Sisitemu yo gucunga ubushyuhe yagupima galvanometerni ingenzi kandi mu gutuma gutunganya ibintu biramba. Itandukaniro ry'ubushyuhe rizatuma galvanometer itemba kandi igabanye uburyo bwo kuyishyira mu mwanya wayo. Ingano zisanzwe ni izi zikurikira. Binyuze mu gukonjesha amazi no gukwirakwiza ubushyuhe, uburyo bwo gutunganya ibintu buramba bushobora kongerwaho 30%.
Agaciro gasanzwe k'ubushyuhe bwa galvanometer
Igikoresho gikonjesha amazi gishobora gukuraho ubushyuhe neza no gutuma galvanometer ikora neza igihe kirekire. Uburyo bw'ingenzi mu bya tekiniki ni ukubona amazi akonjesha adahindagurika cyane binyuze mu buryo bwiza bw'umuyoboro w'amazi akonjesha, no gushushanya imiterere y'igikoresho cyo guhindurira ubushyuhe hanze neza.
Muri sisitemu ya laser ya MOPA pulse yo ku rwego rwa kilowatt ifite imbaraga nyinshi, turasaba cyane ikoreshwa rya lenses za quartz nziza na sisitemu za galvanometer hamwe na sisitemu zo gukonjesha amazi.
Ni gute wahitamo lensi yo gupima imiterere y'izuba?
Ikirahuri cyo mu murima gishyira urumuri rwa laser rwa collimated ku ngingo, cyongera ingufu z'urumuri rwa laser, kandi gikoresha ingufu nyinshi za laser mu gutunganya ibikoresho bitandukanye nko gukata, gushyira ikimenyetso, gusudira, gusukura no gutunganya ubuso.
Ibintu by'ingenzi bigira ingaruka ku bwiza bw'imikorere n'ingaruka za lens yo mu murima ni ibikoresho bya lens yo mu murima n'uburebure bw'impeta ya adaptateri. Ibikoresho by'ingenzi bya lens yo mu murima ni ikirahure na quartz. Itandukaniro riri hagati y'ibi byombi riri mu ngaruka za lens yo mu bushyuhe ku ngufu nyinshi. Nyuma y'uko lens yo mu murima ihora ishyushywa n'imirasire ya laser igihe kirekire, izakora impinduka mu bushyuhe bitewe n'ubwiyongere bw'ubushyuhe, bizatuma optique yoherezwa. Igipimo cyo kugarura urumuri cy'ikintu n'icyerekezo cyo kugarura urumuri cy'ikintu cyo mu kirere gihinduka, kandi ingaruka za lens yo mu bushyuhe zigira ingaruka ku buryo laser n'aho iherereye nyuma yo kugarura urumuri, bizagira ingaruka zikomeye ku ngaruka zo kuvugurura. Quartz ifite coefficient yo kwaguka k'ubushyuhe buke kandi ifite ubushobozi bwo kohereza urumuri bwinshi, bigatuma iba amahitamo meza y'ibikoresho bya lens yo mu murima ifite imbaraga nyinshi. Nibiba ngombwa, module yo gukonjesha amazi igomba kongerwamo.
Impeta ya adaptateri yo guhuza lensi yo mu murima na galvanometer nayo ni ikintu cy'ingenzi bigira ingaruka ku bikoresho no ku mikorere. Uburebure bukwiye bw'impeta ya adaptateri bushobora kwirinda aho lensi yo mu murima igarukira no kwemeza imiterere yo kuyitunganya. Iyo iri hejuru cyane cyangwa hasi cyane, bizatera ibibazo bijyanye nayo.
Muri sisitemu ya laser ya MOPA pulse yo ku rwego rwa kilowatt ifite imbaraga nyinshi, turasaba cyane ikoreshwa ry'indorerwamo za quartz nziza zifite modules zo gukonjesha amazi hamwe n'impeta ya adapter ya field mirror ifite uburebure bukwiye.
Ni gute wahuza lenses zigarura urumuri?
Akamaro k'ingenzi k'ama-lens agarura urumuri mu miterere y'inzira y'urumuri ni uguhindura icyerekezo cy'inzira y'urumuri. Guhitamo ama-lens agarura urumuri meza n'uburyo busanzwe bwo kuyashyiraho bishobora kugira uruhare runini mu bikorwa bimwe na bimwe byihariye, ariko ama-lens meza n'uburyo butari bwo bwo kuyashyiraho nabyo bizatera ikibazo gishya. Imiterere y'ibikoresho bya lens igenwa n'uburebure bw'umuraba n'imbaraga za laser. Substrate muri rusange ikorwa na quartz cyangwa silicon ya crystalline. Filimi igarura urumuri ya laser muri rusange ikorwa na filime y'ifeza cyangwa filime ya dielectric ibonerana, ifite ubushobozi bwo kugarura urumuri bwinshi, ubushobozi bwo kwinjiza urumuri buke no kudakoresha laser. Imiterere y'umubare munini w'ibyangiritse.
Akamenyetso keza k’ikirere ntikazagira ingaruka ku bwiza bw’icyerekezo, ariko mu ikoreshwa nyaryo, ikirere cy’icyerekezo gishobora kwangirika bitewe n’ibintu bitera imbaraga nko gufata vis, nk’indorerwamo y’indorerwamo. Guhindagurika bigira ingaruka cyane cyane ku bwiza bw’ahantu ho gufatisha, bigatera astigmatism yo hasi n’ubundi buryo bwo kugabanya imbaraga. Guhindagurika bibuza ahantu ho gufatisha kugera ku rugero ntarengwa rw’impinduka, bigira ingaruka ku bwiza bw’impinduka n’ingaruka.
Muri sisitemu ya laser ya MOPA pulse yo ku rwego rwa kilowatt ifite imbaraga nyinshi, turasaba cyane gukoresha reflectors za quartz nziza cyane hamwe n'uburyo bukwiye bwo kuyishyiraho kugira ngo irebe ko ingirabuzimafatizo zigumana imbaraga nta guhindagurika.
