Ndi chitukuko chopitilira cha sayansi ndi ukadaulo komanso kufalikira kwa madera osiyanasiyana ogwiritsira ntchito,laserUkadaulo wokonza zinthu pang'onopang'ono ukulowa m'mbali zonse za moyo ndikukhala chida chofunikira kwambiri chokonzera zinthu. Pogwiritsa ntchito ma laser,MOPA ya mulingo wa kilowattMa laser a (Master Oscillator Power-Amplifier) amagwiritsidwa ntchito kwambiri m'magawo monga kukonza zinthu ndi kafukufuku wasayansi chifukwa cha mphamvu zawo zapamwamba kwambiri, kulowa mwamphamvu, komanso kutentha kochepa. Ndi chida chofunikira kwambiri chothandiza mabizinesi kukonza khalidwe ndikuwonjezera zokolola. Chida chabwino kwambiri chogwirira ntchito bwino. Koma chifukwa cha mphamvu zake zapamwamba, kuti laser ya MOPA yotsika kilowatt igwire bwino ntchito, kusankha zowonjezera ndikofunikira. Pokhapokha posankha zowonjezera zoyenera za laser ndi pomwe tingatsimikizire kuti laser ikhoza kugwira ntchito mokhazikika komanso moyenera komanso bwino komanso kukwaniritsa zosowa zosiyanasiyana zogwiritsira ntchito.
Kukhazikika kwamphamvu kwambiri
Kupanga kwakukulu kwa MOPA ya kilowatt-level yokhala ndi magwiridwe antchito apamwamba komanso zizindikiro zaukadaulo
Kuthekera kopanga zinthu zambiri mosalekezama lasers a MOPA amtundu wa kilowatt-level single-modendi chizindikiro chofunikira cha luso la kampani la MOPA laser Research&D, kupanga ndi kupanga. Pakadali pano MAVEN ili ndi mitundu yambiri ya makina amphamvu kwambiri oyeretsera fiber laser a MOPA omwe angakwaniritse zosowa za ntchito zosiyanasiyana m'njira zosiyanasiyana.
Kusintha kwa mphamvu yonse ya maola 24 ndi kochepera <3%
Ubwino wa mtanda umayendetsedwa
Mzere wa Gaussian wa mtundu umodzi Mzere wosalala pamwamba wamitundu yambiri
Ukadaulo wolumikizira chizindikiro cha end-pump, kugawa mphamvu bwino komanso koyenera, njira yapadera yopangira coiling, ndi collimated isolator yamphamvu kwambiri yokhala ndi kristalo yabwino kwambiri yowunikira kutentha, pomwe mphamvu yotulutsa imafika 1000W, imathanso kutsimikizira kuti Beam ndi yabwino kwambiri.
Mu gawo la processing ya fiber laser, makamaka processing yalaser yamphamvu kwambiri ya MOPA nanosecond pulse fiber, chifukwa cha mphamvu yake yapamwamba kwambiri, mphamvu yayikulu ya kugunda kwa mtima komanso kuchuluka kwa ma frequency, kusankha zowonjezera ndikofunikira kwambiri. Zowonjezera zazikulu zomwe zimakhudza momwe laser ya kugunda kwa mtima imagwirira ntchito ndi monga Scanning galvanometer, focusing field mirror ndi reflector.
Kodi mungasankhe bwanji galvanometer yowunikira?
Cholinga cha ukadaulo wa galvanometer scanning ndikumaliza ntchito zowunikira mwachangu komanso molondola. Pali zinthu ziwiri zazikulu zomwe zimatsimikizira. Chimodzi ndi njira yowongolera yomwe imatha kukwaniritsa liwiro lalikulu komanso molondola kwambiri, ndipo china ndi galvanometer yokhala ndi liwiro loyankha mwachangu. Kapangidwe ka galvanometer makamaka kamakhala ndi magawo atatu: chowunikira, mota ndi khadi yoyendetsera, pakati pawo lenzi ndi yofunika kwambiri kuti ntchitoyo ikhale yokhazikika.
Zipangizo za lenzi ya Galvanometer ndi zizindikiro zokhudzira
Dongosolo loyang'anira kutentha kwagalvanometer yowunikiraNdi chinthu chofunikira kwambiri pakutsimikizira kukhazikika kwa ntchito yokonza kwa nthawi yayitali. Kusiyana kwa kutentha kudzapangitsa kuti galvanometer isunthike ndikuchepetsa kulondola kwa malo. Makhalidwe abwino ndi awa. Kudzera mu kuzizira kwa madzi ndi kutayika kwa kutentha, kukhazikika kwa ntchito yokonza kwa nthawi yayitali kumatha kukulitsidwa ndi 30%.
Mtengo wamba wa kutentha kwa galvanometer
Chipangizo choziziritsira madzi chimatha kuchotsa kutentha bwino ndikuwonetsetsa kuti galvanometer ikugwira ntchito bwino kwa nthawi yayitali. Njira zazikulu zaukadaulo ndikupeza malo ozizira amadzi ozizira omwe sagwedezeka kwambiri kudzera mu kapangidwe kabwino ka njira yozizira yamadzi, komanso kupanga kapangidwe ka chipangizo chosinthira kutentha chakunja.
Mu makina amphamvu kwambiri a MOPA pulse laser omwe ali ndi kilowatt, tikukulimbikitsani kwambiri kugwiritsa ntchito magalasi apamwamba a quartz ndi makina a galvanometer okhala ndi makina ozizira amadzi.
Kodi mungasankhe bwanji lenzi yowunikira?
Lenzi ya m'munda imayang'ana kuwala kwa laser komwe kumapangidwa pamalo enaake, kumawonjezera mphamvu ya kuwala kwa laser, ndipo imagwiritsa ntchito mphamvu zambiri za laser pokonza zinthu zosiyanasiyana monga kudula, kulemba, kuwotcherera, kuyeretsa ndi kukonza pamwamba.
Zinthu zazikulu zomwe zimakhudza ubwino wa lenzi ya kumunda ndi zotsatira zake ndi zinthu zomwe zili mu lenzi ya kumunda ndi kutalika kwa mphete ya adaputala. Zipangizo zazikulu za lenzi ya kumunda ndi galasi ndi quartz. Kusiyana pakati pa ziwirizi kuli mu mphamvu ya lenzi ya kutentha pa mphamvu yayikulu. Lenzi ya kumunda ikayang'aniridwa nthawi zonse ndi kuwala kwa laser kwa nthawi yayitali, imapanga kusintha kwa kutentha chifukwa cha kutentha kwakukulu, komwe kungayambitse ma transmission optics. Chizindikiro cha refractive cha chinthucho ndi njira yowunikira ya chinthu chowunikira kusintha, ndipo mphamvu ya lenzi ya kutentha idzakhudza momwe laser imagwirira ntchito komanso malo owunikira pambuyo powunikira, zomwe zidzakhudza kwambiri mphamvu ya processing. Quartz ili ndi coefficient yotsika ya kutentha komanso transmittance yayikulu, zomwe zimapangitsa kuti ikhale chisankho chabwino cha zinthu zamagetsi amphamvu kwambiri. Ngati pakufunika, gawo loziziritsira madzi liyenera kuwonjezedwa.
Mphete ya adaputala yogwirizanitsa lenzi yamunda ndi galvanometer ndi chinthu chofunikira chomwe chimakhudza zida ndi ntchito yokonza. Kutalika koyenera kwa mphete ya adaputala kumatha kupewa malo obwerera a lenzi yamunda ndikutsimikizira mtundu wa ntchito yokonza. Ngati ili yokwera kwambiri kapena yotsika kwambiri, ingayambitse mavuto ofanana.
Mu makina amphamvu kwambiri a MOPA pulse laser a kilowatt, tikulimbikitsa kwambiri kugwiritsa ntchito magalasi apamwamba kwambiri a quartz okhala ndi ma modules ozizira madzi ndi mphete yapadera ya adapter ya galasi lamunda yokhala ndi kutalika koyenera.
Kodi mungagwirizanitse bwanji magalasi owunikira?
Ntchito yaikulu ya magalasi owunikira mu kapangidwe ka njira yowunikira ndikusintha njira yowunikira. Kusankha magalasi owunikira abwino komanso njira zokhazikika zoyikira kungathandize kwambiri pa ntchito zina zapadera, koma magalasi abwino komanso njira zosamveka bwino zoyikira zingayambitsenso funso latsopano. Makhalidwe a lens amatsimikiziridwa ndi kutalika kwa nthawi ndi mphamvu ya laser. Gawo la pansi nthawi zambiri limapangidwa ndi quartz yosakanikirana kapena silicon yopyapyala. Filimu yowunikira ya laser nthawi zambiri imapangidwa ndi filimu yasiliva kapena filimu yowonekera ya dielectric, yomwe imakhala ndi kuwala kwakukulu, kuthamanga kochepa kwa kuyamwa komanso kukana kwa laser. Makhalidwe a malire owonongeka kwambiri.
Chowunikira bwino cha ndege sichidzakhudza khalidwe la kuyang'ana, koma pakugwiritsa ntchito kwenikweni, gawo lowunikira likhoza kusokonekera chifukwa cha zinthu zomangika monga kukhazikika kwa zomangira, mofanana ndi galasi lozungulira. Kusokonekera kumeneku kumakhudza kwambiri khalidwe la malo owunikira, zomwe zimayambitsa astigmatism yotsika komanso astigmatism ina yotsika. Kusokonekera kumeneku kumalepheretsa malo owunikira kufika pamalire a diffraction, zomwe zimakhudza khalidwe la kukonza ndi zotsatira zake.
Mu makina amphamvu kwambiri a MOPA pulse laser a kilowatt, tikulimbikitsa kwambiri kugwiritsa ntchito ma quartz reflectors apamwamba komanso njira zoyenera zoyikira kuti magalasi azigwira ntchito popanda kusintha.
