Ndi chitukuko chosalekeza cha sayansi ndi ukadaulo komanso kukula kwa magawo osiyanasiyana ogwiritsira ntchito,laserumisiri processing pang'onopang'ono akulowa m'magulu onse a moyo ndi kukhala yofunika processing chida. Pogwiritsa ntchito ma laser,kilowatt-level MOPA(Master Oscillator Power-Amplifier) lasers amagwiritsidwa ntchito kwambiri m'magawo monga kukonza zinthu ndi kuyesa kafukufuku wasayansi chifukwa cha mphamvu zawo zapamwamba, kulowa mwamphamvu, komanso kutsika kwamafuta. Ndi chida chofunikira chothandizira mabizinesi kukweza bwino komanso kukulitsa zokolola. Chida chabwino chachangu. Koma ndendende chifukwa cha mphamvu zake zazikulu, kuti muwonjezere kuwongolera kwa laser ya kilowatt-level MOPA, kusankha kwa Chalk ndikofunikira. Pokhapokha posankha zida zoyenera za laser tingatsimikizire kuti laser imatha kugwira ntchito mokhazikika komanso mogwira mtima komanso kukwaniritsa zosowa zosiyanasiyana zamagwiritsidwe ntchito.
Kukhazikika kwamphamvu kwamphamvu
Kupanga kwakukulu kwa kilowatt-level MOPA yokhala ndi magwiridwe antchito apamwamba komanso zizindikiro zaukadaulo
Kutha kupanga mokhazikika pakubalama lasers a MOPA amtundu wa kilowatt-level single-modendi chizindikiro chofunikira cha kampani ya MOPA laser R&D, kupanga ndi kupanga. MAVEN pakadali pano ili ndi mitundu ingapo yamakina apamwamba kwambiri a MOPA CHIKWANGWANI cha laser chotsuka chomwe chimatha kukwaniritsa zosowa zantchito zosiyanasiyana m'magawo angapo.
Kusinthasintha kwamphamvu kokwanira kwa 24h ndikochepera <3%
Beam khalidwe controlable
Mtengo umodzi wa Gaussian Multi-mode flat-top mtengo
Ukadaulo wophatikiza ma siginecha a pampu yomaliza, kugawa kwamphamvu kwambiri komanso koyenera, njira yapadera yopangira makina opangira magetsi, komanso makina opangira ma collimated a single-mode high-power collimated ndi kristalo wowoneka bwino wa kutentha, pomwe mphamvu yotulutsa imafika ku 1000W, imathanso kuwonetsetsa kuti Beam yabwino kwambiri.
M'munda wa CHIKWANGWANI laser processing, makamaka processing wahigh-mphamvu MOPA nanosecond kugunda CHIKWANGWANI laser, chifukwa cha mphamvu zake zapamwamba, mphamvu yaikulu ya pulse ndi maulendo apamwamba, kusankha kwa zipangizo ndizofunikira kwambiri. Chalk chachikulu chomwe chimakhudza magwiridwe antchito amphamvu yamphamvu ya laser pulse ndi Scanning galvanometer, kuyang'ana galasi lakumunda ndi chowunikira.
Kodi kusankha galvanometer kupanga sikani?
Cholinga cha ukadaulo wa galvanometer kupanga sikani ndi kumaliza ntchito zojambulira mwachangu, zolondola kwambiri. Pali zinthu ziwiri zazikulu zomwe zimatsimikizira. Imodzi ndi dongosolo lolamulira lomwe lingathe kukwaniritsa kuthamanga kwambiri komanso kulondola kwambiri, ndipo linalo ndi galvanometer yokhala ndi liwiro lofulumira. scanner. Mapangidwe a galvanometer makamaka amakhala ndi magawo atatu: chowunikira, galimoto ndi khadi yoyendetsa, yomwe mandala ndi ofunika kwambiri kuti pakhale bata.
Galvanometer mandala zinthu ndi zizindikiro zokopa
Thermal management system of thekusanthula galvanometerndi chinthu chofunika kwambiri kuonetsetsa kuti nthawi yaitali processing bata. Kusiyana kwa kutentha kumapangitsa kuti galvanometer isunthike ndikuchepetsa kulondola kwa malo. Makhalidwe abwino ndi awa. Kupyolera mu kuziziritsa kwamadzi kutentha kwachangu, kukhazikika kwa nthawi yayitali kumatha kupitilizidwa ndi 30%.
Mtengo wa galvanometer wofanana ndi kutentha
Chipangizo chozizirira madzi chimatha kuchotsa kutentha ndikuonetsetsa kuti galvanometer ikugwira ntchito kwa nthawi yayitali. Njira zazikuluzikulu zaukadaulo ndikupeza malo oziziritsa amadzi ocheperako kudzera munjira yowongoleredwa ya njira yamadzi ozizira, komanso kupanga chida chakunja chosinthira kutentha kwakunja.
Mu kilowatt-level high-power MOPA pulse laser system, timalimbikitsa mwamphamvu kugwiritsa ntchito magalasi apamwamba kwambiri a quartz ndi makina a galvanometer okhala ndi machitidwe ozizirira madzi.
Kodi mungasankhire bwanji mandala akumunda?
Magalasi akumunda amayang'ana pamtengo wophatikizika wa laser pamfundo, kumawonjezera kuchuluka kwamphamvu kwa mtengo wa laser, ndipo amagwiritsa ntchito mphamvu yayikulu ya laser kuti achite zinthu zosiyanasiyana monga kudula, kuyika chizindikiro, kuwotcherera, kuyeretsa ndi kuchiritsa pamwamba.
Mfundo zazikuluzikulu zomwe zimakhudza khalidwe la processing ndi zotsatira za lens kumunda ndi zinthu za lens munda ndi kutalika kwa adaputala mphete. Zida zazikulu zamagalasi akumunda ndi galasi ndi quartz. Kusiyana pakati pa awiriwa kwagona mu mphamvu ya lens yotentha pa mphamvu zambiri. Pambuyo poyang'ana ma lens akuwunikira mosalekeza ndi mtengo wa laser kwa nthawi yayitali, imatulutsa matenthedwe chifukwa cha kuchuluka kwa kutentha, komwe kumayambitsa ma optics opatsirana. Mlozera wa refractive wa chinthucho ndi mayendedwe owunikira akusintha kwa zinthu zowoneka bwino, ndipo ma lens otentha amakhudza mawonekedwe a laser ndi malo omwe amayang'ana pambuyo poyang'ana, zomwe zingakhudze kwambiri magwiridwe antchito. Quartz ili ndi mphamvu yowonjezera yowonjezera kutentha komanso kufalikira kwakukulu, zomwe zimapangitsa kukhala chisankho chabwinoko pamagalasi akumunda amphamvu kwambiri. Ngati ndi kotheka, gawo loziziritsa madzi liyenera kuwonjezeredwa.
Mphete yofananira ndi mandala akumunda ndi galvanometer ndi chinthu chofunikira chomwe chimakhudza zida ndi kukonza. Kutalika koyenera kwa mphete ya adaputala kumatha kupewa malo obwereranso a mandala akumunda ndikuwonetsetsa mawonekedwe opangira. Ngati ili yokwera kwambiri kapena yotsika kwambiri, imayambitsa mavuto ofanana.
Mu kilowatt-level high-power MOPA pulse laser systems, timalimbikitsa kwambiri kugwiritsa ntchito magalasi apamwamba kwambiri a quartz okhala ndi ma modules oziziritsa madzi ndi mphete yodzipatulira yodzipatulira ya magalasi oyenerera.
Kodi mungafanane bwanji ndi magalasi owunikira?
Ntchito yaikulu ya magalasi owonetsera mu mawonekedwe a njira ya kuwala ndikusintha njira ya kuwala. Kusankha magalasi owoneka bwino komanso njira zoyikitsira zokhazikika kumatha kukhala ndi gawo lalikulu pamapulogalamu ena apadera, koma magalasi abwinobwino komanso njira zoyikitsira zosamveka zingayambitsenso Funso Latsopano. Makhalidwe a lens amatsimikiziridwa ndi kutalika kwake ndi mphamvu ya laser. Gawo lapansili nthawi zambiri limapangidwa ndi quartz yosakanikirana kapena silicon ya crystalline. Kanema wowunikira wa laser nthawi zambiri amapangidwa ndi filimu yasiliva kapena filimu yowonekera ya dielectric, yomwe imakhala ndi mawonekedwe apamwamba, kutsika kochepa komanso kukana kwa laser. Mawonekedwe a kuwonongeka kwakukulu kolowera.
Chowonetsera bwino cha ndege sichingakhudze momwe mukuwonera, koma pogwiritsira ntchito, ndege yowonetsera ikhoza kukhala yopunduka chifukwa cha zovuta monga kukhazikika kwa screw, kofanana ndi galasi la cylindrical. Kupotozako kumakhudza makamaka mawonekedwe a malo, kumayambitsa astigmatism yotsika komanso ena otsika astigmatism. Aberration imalepheretsa malo omwe akuyang'ana kuti asafikire malire a diffraction, zomwe zimakhudza ubwino ndi zotsatira zake.
M'makilowati amphamvu kwambiri a MOPA pulse laser system, timalimbikitsa kwambiri kugwiritsa ntchito zowunikira zapamwamba za quartz ndi njira zoyikira zoyenera kuti magalasi agwire mwamphamvu popanda kupunduka.
