Monga njira yoyeretsera yogwira mtima komanso yosawononga chilengedwe,ukadaulo woyeretsa ndi laserPang'onopang'ono ikulowa m'malo mwa njira zoyeretsera mankhwala ndi makina. Chifukwa cha malamulo okhwima kwambiri oteteza chilengedwe mdziko muno komanso kufunafuna koyeretsa bwino komanso kogwira mtima m'mafakitale opanga zinthu, kufunikira kwa msika waukadaulo woyeretsa ndi laser kukukula mofulumira. Monga dziko lalikulu lopanga zinthu, China ili ndi maziko akuluakulu a mafakitale, omwe amapereka malo ambiri ogwiritsira ntchito ukadaulo woyeretsa ndi laser. Mu ndege, sitima, kupanga magalimoto, kupanga nkhungu ndi mafakitale ena, ukadaulo woyeretsa ndi laser wakhala ukugwiritsidwa ntchito kwambiri ndipo pang'onopang'ono ukufalikira ku mafakitale ena.
Ukadaulo woyeretsa pamwamba pa chinthu chogwiritsidwa ntchito umagwiritsidwa ntchito kwambiri m'magawo ambiri. Njira zoyeretsera zachikhalidwe nthawi zambiri zimakhala kuyeretsa kokhudzana ndi chinthu, komwe kumagwiritsa ntchito mphamvu yamakina pamwamba pa chinthu chomwe chikuyeretsedwa, kuwononga pamwamba pa chinthucho kapena choyeretsera chimamatira pamwamba pa chinthu chomwe chikuyeretsedwa ndipo sichingachotsedwe. , zomwe zimayambitsa kuipitsa kwina. Masiku ano, dzikolo limalimbikitsa chitukuko cha mafakitale atsopano obiriwira komanso osawononga chilengedwe, ndipo kuyeretsa pogwiritsa ntchito laser ndiye chisankho chabwino kwambiri. Kuyeretsa pogwiritsa ntchito laser kosawononga komanso kosakhudza kumathetsa mavutowa. Zipangizo zoyeretsera pogwiritsa ntchito laser ndizoyenera kuyeretsa zinthu zopangidwa ndi zipangizo zosiyanasiyana ndipo zimaonedwa kuti ndi njira yodalirika komanso yothandiza kwambiri yoyeretsera.
Kuyeretsa ndi lasermfundo
Kuyeretsa pogwiritsa ntchito laser ndiko kuunikira kuwala kwa laser komwe kumakhala ndi mphamvu zambiri ku gawo la chinthu chomwe chikuyeretsedwa, kuti laser ilowereredwe ndi gawo loipitsidwa ndi substrate. Kudzera mu njira monga kuchotsa kuwala ndi kupopera, kumamatira pakati pa zodetsa ndi substrate kumathetsedwa, kotero kuti zodetsazo zimachoka pamwamba pa chinthucho kuti zikwaniritse cholinga choyeretsa popanda kuwononga chinthucho.
Chithunzi 1: Chithunzi chojambula cha kuyeretsa pogwiritsa ntchito laser.
Pankhani yoyeretsa pogwiritsa ntchito laser, ma fiber laser akhala opambana pakati pa magwero a kuwala pogwiritsa ntchito laser chifukwa cha mphamvu zawo zosinthira kuwala pogwiritsa ntchito photoelectric, khalidwe labwino kwambiri la kuwala, magwiridwe antchito okhazikika komanso chitukuko chokhazikika. Ma fiber lasers amaimiridwa ndi mitundu iwiri: ma pulsed fiber lasers ndi continuous fiber lasers, omwe ali ndi malo otsogola pamsika pakupanga zinthu zazikulu komanso kukonza zinthu molondola motsatana.
Chithunzi 2: Kapangidwe ka laser ya ulusi wozungulira.
Kuyerekeza Kugwiritsa Ntchito Kuyeretsa kwa Laser Yopukutidwa ndi Ulusi Wopitirira muyeso
Pa ntchito zatsopano zoyeretsera laser, anthu ambiri angasokonezeke pang'ono akakumana ndi ma pulse laser ndi ma continuous laser omwe ali pamsika: Kodi ayenera kusankha ma pulse fiber laser kapena ma continuous fiber lasers? Pansipa, mitundu iwiri yosiyanasiyana ya ma laser imagwiritsidwa ntchito pochita zoyeserera zochotsa utoto pamwamba pa zinthu ziwiri, ndipo magawo abwino kwambiri oyeretsera laser ndi zotsatira zabwino zoyeretsera zimagwiritsidwa ntchito poyerekeza.
Pogwiritsa ntchito makina oonera zinthu m'ma microscope, chitsulo cha pepala chimasungunuka pambuyo poti chakonzedwa ndi laser yamphamvu kwambiri yopitilira muyeso. Chitsulocho chitakonzedwa ndi laser ya MOPA pulse fiber, zinthu zoyambira zimawonongeka pang'ono ndipo kapangidwe ka zinthu zoyambira kamasungidwa; chitsulocho chitakonzedwa ndi laser yanthawi zonse yopitilira muyeso, kuwonongeka kwakukulu ndi zinthu zosungunuka zimapangidwa.
Laser ya MOPA pulsed fiber (kumanzere) Laser ya CW fiber (kumanja)
Laser ya ulusi wopunduka (kumanzere) Laser ya ulusi wopitilira (kumanja)
Kuchokera kufananiza komwe kwatchulidwa pamwambapa, zitha kuwoneka kuti ma laser opitilira muyeso amatha kuyambitsa kusintha kwa mtundu ndi kusintha kwa substrate chifukwa cha kutentha kwakukulu komwe amalowetsa. Ngati zofunikira pakuwonongeka kwa substrate sizili zazikulu ndipo makulidwe a zinthu zomwe ziyenera kutsukidwa ndi ochepa, mtundu uwu wa laser ungagwiritsidwe ntchito ngati gwero la kuwala. Laser yopukutidwa imadalira mphamvu yayikulu komanso ma pulses obwerezabwereza kuti igwire ntchito pazinthu, ndipo nthawi yomweyo imayatsa ndi kusuntha zinthu zotsukira kuti zichotsedwe; imakhala ndi mphamvu zochepa zotenthetsera, imagwirizana kwambiri, komanso imalondola kwambiri, ndipo imatha kukwaniritsa ntchito zosiyanasiyana. Kuwononga mawonekedwe a substrate.
Kuchokera pa mfundo iyi, poganizira kulondola kwambiri, ndikofunikira kuwongolera kutentha kwa substrate, ndipo pazochitika zomwe zimafuna kuti substrate ikhale yosawononga, monga aluminiyamu yopakidwa utoto ndi chitsulo cha nkhungu, tikukulimbikitsani kusankha laser ya pulse fiber; pa zipangizo zina zazikulu za aluminiyamu zolimba kwambiri, mapaipi ozungulira, ndi zina zotero. Chifukwa cha kukula kwawo kwakukulu komanso kutentha mwachangu, komanso kufunikira kochepa pakuwonongeka kwa substrate, ma laser a ulusi wopitilira amatha kusankhidwa.
In kuyeretsa ndi laser, mikhalidwe ya zinthu iyenera kuganiziridwa mokwanira kuti zitsimikizire kuti zosowa zoyeretsera zakwaniritsidwa ndikuchepetsa kuwonongeka kwa substrate. Malinga ndi mikhalidwe yeniyeni yogwirira ntchito, ndikofunikira kusankha gwero loyenera la kuwala kwa laser.
Ngati kuyeretsa kwa laser kukufuna kugwiritsidwa ntchito kwambiri, sikungasiyanitsidwe ndi luso lamakono ndi njira zatsopano. Maven apitiliza kutsatira malo a laser +, kuwongolera liwiro la chitukuko mosalekeza, kuyesetsa kukulitsa ukadaulo wa gwero la kuwala kwa laser, ndikuyang'ana kwambiri pakuthetsa zida zofunika za laser ndi nkhani zazikulu za zigawo zimapereka gwero lamphamvu popanga zinthu zapamwamba.
