Laser yog ib qho tseem ceeb ntawm cov kev tshawb fawb txog ntuj tsim ntawm lub xyoo pua nees nkaum. Hauv xyoo 1960, thawj laser tau tsim nyob hauv lub ntiaj teb. Tom qab, lasers nrog kev sib haum xeeb, cov yeeb ncuab me me, thiab siab zog concentration tau dav dav siv nyob rau ntau thaj chaw, xws li laser ntau, laser processing, thiab laser kev sib txuas lus. Lub sijhawm thaum 1980s, tibneeg pib siv hluav taws xob laser hluav taws xob ua kom pom kev ua haujlwm ntawm qhov chaw ua haujlwm, ua rau ntawm qhov av, xeb lossis txheej kom ntom nti los yog tev tawm, thiab tshem tawm cov txuas los yog txheej nyob rau ntawm qhov chaw qhov khoom ntawm kev kub ceev. Cov txheej txheem ntawm tu lub qhov ntawm cov khoom yog laser tu. Txij li kaum xyoo dhau los, laser tu tau tsiv tawm ntawm kev sim mus rau cov ntawv siv, siv ntau yam roj hmab khoom pwm, silicone khoom moulds kom tshem tawm cov roj, xeb, kab lis kev cai relics, microelectron circuit boards thiab lwm cov ntaub ntawv tu, thiab tau zoo heev Nyiaj txiag thiab social benefits.
Nyob rau hauv nruab nrab xyoo 1980s, kom tau cov kev xav tau ntawm cov khoom tsim tawm cov khoom siv me me ntawm cov qauv kev nco, laser tu tau txais ntau xim thiab kev tshawb fawb thiab tau txais kev lees paub thiab tau lees paub tias yog ib txoj kev zoo tu cov neeg tshawb xyuas tau sim siv. Pa ntxuav kev xws li kho vaj tsev, tshuaj ntxuav tu, thiab ultrasonic tu kom tshem cov xa raws sab nraud txuas rau lub qauv yog tsawg dua tagnrho. Txij li cov quab yuam tawm ntawm cov qauv ntawm lub voj voog nyob rau hauv lub voj voog ntawm cov qauv ntawm lub voj voog ntawm cov qauv ntawm lub voj voog ntawm tus qauv ntawm lub voj voog ntawm tus qauv (hu ua van der Waals force, electrostatic force, etc.) lub ntiajteb txawj nqus, thiab kev kho txhua yam tsis tuaj yeem ua tiav. Qhov kev tshem tawm me me, cov tshuaj ntxuav tau ua rau corrosion thiab recontamination ntawm template. Ultrasonic tu kom tus template kom muab tso rau hauv qhov chaw ntawm sonic kev co, uas yuav ua rau lub template rau rupture. Laser tu yog tsim nyob rau hauv xws li txoj kev tshwm sim. Nyob rau hauv cov ntaub ntawv no, cov neeg pib kawm ntawv nws: nws cov tsos tau daws qhov teeb meem ntawm cov kabmob ntawm lub npoo ntawm lub qauv, thiab nrog rau kev tsim kho lub tshuab laser tu, Nws kuj tau dav siv ntau lwm cov hauj lwm.
Nyob rau xyoo 1980s, cov kws tshawb fawb tau pom tias npog lub npoo ntawm cov substrate nrog cov kua dej ntim cov kua dej muaj ntau txoj hauv kev tshem tawm cov kab mob phem. Ntawm lawv, dej yog ib qho zoo ntim cov txheej txheem. Txoj kev los npog qhov chaw ntawm qhov tshooj yuav tsum tau muab ntxuav nrog ib zaj duab xis ua kua uas muaj txheej txheem ntawm qhov kev txiav txim ntawm millimeters thiab mam li irradiating nrog ib lub laser kom tshem tawm cov kab mob tsis zoo yog dab tsi peb mam li hu lub qhov cub (ntub) laser tu, piv nrog yam qhuav. Laser tu, lub laser tu tau tu ntau dua kev ua haujlwm. Nws tsis yog txog thaum ntxov 1990s uas laser tu yeej nkag nkag industrial ntau lawm. Nyob rau hauv qhov tseeb, yuav luag nyob rau hauv 1987, peb cov pab pawg neeg tshawb fawb ntawm nws tus kheej pom cov teebmeem ntawm kev haus luam yeeb. Ntawm lawv, cov pab pawg neeg tshawb fawb tau coj los ntawm Zapka tau txais thawj patent rau laser tu thiab lees paub nws daim ntawv thov kev lag luam hauv kev lag luam. Lwm qhov kev tshawb nrhiav yog Max Planck lub koom haum rau Biochemistry thiab Physics nyob rau hauv Toku, cov kws tshawb fawb Cov txheej txheem silicon tau them nrog cov khoom kub muaj 35 nm, thiab tom qab ntawd cov roj nitrogen molecular tau ncaj qha irradiated rau cov khoom nto, cov khoom kub ntawm lub nplaim tau ntse muab tshem tawm, thaum lub silicon template tsis puas, qhia tias lub laser tau siv los ntxuav cov khoom nto. Cov tshuaj phem raug ua tau.
Nyob rau xyoo 2001, Fourrier thiab nws cov neeg ua haujlwm tau siv cov chav ua haujlwm ntawm qhov sib txawv ntawm qhov sib txawv, qhov ntau thiab tsawg, thiab cov ntaub ntawv kom pom cov laser siv rau ntau qhov sib txawv hauv qhov ntau ntawm kaum tawm rau pua pua ntawm nanometers. Qhov chaw pib yog tib yam. Qhov "zoo tshaj plaws tus Harbor" muab ib qho txiaj ntsim ntau ntxiv rau kev siv lub tshuab ua kom lub laser tu kom tshem tau cov micron micron. Txawm hais tias kev tsim kho laser tu raws li kev ntxuav ntawm cov khoom me me ntawm qhov chaw, kev tshawb fawb ntawm lwm daim ntaub ntawv tau raug ua tiav raws li. Piv txwv li, thaum xyoo 1970, tom qab kev tshawb fawb thiab kev sim, nws pom tias lasers yog tu vaj tse thiab duab kos. Muaj kev ua tau. Nyob rau xyoo 1992, UNESCO tau siv kho lub Yasmin Cathedral hauv As Kiv. Muaj qee lub tebchaws nyob rau Tebchaws Europe kuj tau ua kom lub Amiens Cathedral (Fabkis), St Stephan Cathedral (Vienna, Austria), lub qhov ntxa ntawm Unknown Soldier (Warsaw, Poland). Daim ntawv thov ntawm laser hauv stripping muaj kuj attracted cov xim ntawm kev soj ntsuam ntawm. Woodroffe li al. hauv Tebchaws Meskas tau ua ntau yam haujlwm hauv thaj chaw no.
Nyob rau xyoo 1990, cov neeg tshawb nrhiav nyob hauv lub teb chaws Yelemees thiab Nyiv tsim tau cov tshuab hluav taws xob TEA-CO2 rau cov xim pleev xim laser, thiab siv lawv ua ntau yam kev sim. Nws tsis txog txij li xyoo 2005 uas cov kws tshawb fawb tau luam tawm cov ntaub ntawv ntawm kev siv lub tshuab dav hlau uas siv cov hluav taws xob TEA-CO2 lasers. Cov kws tshawb fawb los ntawm ntau lub teb chaws kuj tau tshawb nrhiav ntau ntawm kev tshawb fawb ntawm cov ntaub moulds, kev kho deg, qhov chaw khib nyiab thiab lwm yam, thiab ua tiav cov txiaj ntsim tau zoo.
