Kule mihla, imakethi yelaser ilawulwa ziilaser zefayibha ezidlula iilaser ze-UV. Usetyenziso olubanzi lwemizi-mveliso luthethelela into yokuba iilaser zefayibha zithatha isabelo esikhulu semarike. Ngokuphathelele iilaser ze-UV, zisenokungasebenzi njengeelaser zefayibha kwiindawo ezininzi ngenxa yemida yazo, kodwa luphawu oluthile lobude be-355nm oluhlukanisa iilaser ze-UV kwezinye iilaser, okwenza iilaser ze-UV zibe lukhetho lokuqala kwizicelo ezithile ezikhethekileyo.
I-laser ye-UV ifezekiswa ngokubeka indlela yesithathu yokuvelisa i-harmonic ekukhanyeni kwe-infrared. Ngumthombo wokukhanya okubandayo kwaye indlela yayo yokucubungula ibizwa ngokuba yi-cold processing. Ngobubanzi be-wavelength kunye ne-pulse kunye nokukhanya okusemgangathweni ophezulu, ii-laser ze-UV zinokufikelela kwi-micromachining echanekileyo ngakumbi ngokuvelisa indawo ye-laser egxile ngakumbi kwaye zigcine eyona ndawo incinci ichaphazela ubushushu. Ukufunxwa ngamandla aphezulu kwee-laser ze-UV, ngakumbi ngaphakathi kobubanzi be-wavelength ye-UV kunye ne-short pulse, kuvumela izixhobo ukuba zitshise ngokukhawuleza ukuze kuncitshiswe i-Wavelength ye-UV kunye ne-carbonization. Ukongeza, indawo encinci yokugxila ivumela ii-laser ze-UV ukuba zisetyenziswe kwindawo yokucubungula echanekileyo nencinci. Ngenxa ye-Wavelength ye-Wavelength encinci kakhulu, i-UV laser processing ihlelwe njenge-cold processing kwaye yenye yezona zinto zibalaseleyo ze-UV laser ezahluka kwezinye ii-laser. I-UV laser inokufikelela ngaphakathi kwezinto, kuba isebenzisa i-photochemical reaction ekuqhubekeni. I-wavelength ye-UV laser imfutshane kune-wavelength ebonakalayo. Nangona kunjalo, yile mfutshane yamaza e-UV evumela ii-UV lasers ukuba zigxile ngokuchanekileyo ukuze ii-UV lasers zikwazi ukwenza ukucubungula okuchanekileyo okuphezulu kwaye zigcine ukuchaneka okumangalisayo kokubeka izinto ngaxeshanye.
Iilaser ze-UV zisetyenziswa kakhulu ekuphawuleni nge-elektroniki, ekuphawuleni kwikhabhathi yangaphandle yezixhobo zasekhaya ezimhlophe, ekuphawuleni umhla wokuveliswa kokutya namayeza, eluswini, kumsebenzi wezandla, ekusikeni ilaphu, kwimveliso yerabha, kwizinto zeglasi, kwipleyiti yegama, kwizixhobo zonxibelelwano njalo njalo. Ukongeza, iilaser ze-UV zingasetyenziswa nakwiindawo zokucubungula eziphezulu nezichanekileyo, ezifana nokusika i-PCB kunye nokubhola kunye nokubhala nge-ceramics. Kubalulekile ukukhankanya ukuba i-EUV yeyona ndlela yokucubungula i-laser ekwaziyo ukusebenza kwi-7nm chip kwaye ukubakho kwayo kwenza uMthetho kaMoore uhlale ukho nanamhlanje.
Kwiminyaka emibini edlulileyo, imakethi yelaser ye-UV iphuhlile ngokukhawuleza. Ngaphambi kowama-2016, inani lilonke lee-laser ze-UV zasekhaya lalingaphantsi kweeyunithi ezingama-3000. Nangona kunjalo, ngo-2016, eli nani landa kakhulu laya kwiiyunithi ezingaphezu kwama-6000 kwaye ngo-2017, inani lanyuka laya kwiiyunithi ezingama-9000. Uphuhliso olukhawulezileyo lwemakethi yelaser ye-UV lubangelwa kukwanda kwemfuno yemarike yezicelo zokucubungula eziphezulu ze-UV laser. Ukongeza, ezinye izicelo ezazilawulwa ziilaser ze-YAG kunye neelaser ze-CO2 ngaphambili ngoku zithathelwe indawo ziilaser ze-UV.
Kukho iinkampani ezininzi zasekhaya ezivelisa kwaye zithengisa ii-laser ze-UV, kuquka iHuaray, i-Inngu, i-Bellin, i-Logan, i-Maiman, i-RFH, i-Inno, i-DZD Photonics kunye ne-Photonix. Ngo-2009, indlela ye-laser ye-UV yasekhaya yayisekuqaleni kophuhliso, kodwa ngoku sele ivuthiwe. Iinkampani ezininzi ze-laser ye-UV ziye zaqaphela ukuveliswa ngobuninzi, nto leyo eyaphula ulawulo lweebhrendi zangaphandle kwii-laser ze-UV eziqinileyo kwaye yehlisa kakhulu ixabiso lee-laser ze-UV zasekhaya. Ixabiso eliphantsi kakhulu likhokelela ekuthandweni ngakumbi kwe-UV laser processing, nto leyo enceda ukuphucula inqanaba lokucubungula lasekhaya. Nangona kunjalo, kufanelekile ukukhankanya ukuba abavelisi basekhaya bagxile kakhulu kwii-laser ze-UV ezinamandla aphakathi ukusuka kwi-1W-12W. (I-Huaray iphuhlise ii-laser ze-UV ezingaphezu kwe-20W.) Ngelixa kwii-laser ze-UV ezinamandla aphezulu, abavelisi basekhaya abakakwazi ukuvelisa, beshiya ngasemva iimpawu zangaphandle.
Ngokuphathelele iimpawu zamanye amazwe, iSpectral-Physics, iCoherent, iTrumpf, iAOC, iPowerlase kunye neIPG ngabadlali abaphambili kwiimarike ze-UV laser zaphesheya. ISpectral-Physics iphuhlise ii-UV lasers ezinamandla aphezulu ezingama-60W (M2 <1.3) ngelixa iPowerlase inee-DPSS 180W UV lasers (M2<30). Ngokuphathelele i-IPG, umthamo wayo wokuthengisa wonyaka ufikelela phantse kwizigidi ezilishumi ze-RMB kwaye i-fiber laser yayo ibandakanya ngaphezulu kwe-50% yesabelo semarike semarike ye-fiber laser yaseTshayina. Nangona umthamo wokuthengisa wee-UV lasers eTshayina ubandakanya inxalenye encinci kumthamo wayo wokuthengisa xa uthelekiswa nowee-fiber lasers, i-IPG isacinga ukuba ii-UV lasers zaseTshayina ziya kuba nekamva elithembisayo, elixhaswa yimfuno ekhulayo yezicelo zokucubungula izixhobo ze-elektroniki zabathengi eTshayina. Kwikota edlulileyo, i-IPG ithengise i-UV laser engaphezulu kwesigidi seedola zaseMelika. I-IPG inethemba lokukhuphisana neSpectral-Physics eyinkampani engaphantsi kweMKS kweli candelo lithile kwaye i-DPSSL yendabuko ngakumbi.
Ngokubanzi, nangona ii-laser ze-UV zingathandwa njengee-laser zefayibha, ii-laser ze-UV zisenekamva elithembisayo kwizicelo nakwiimfuno zemarike, nto leyo enokubonwa kukonyuka okukhulu komthamo wokuthunyelwa kwiminyaka emi-2 edlulileyo. Ukucutshungulwa kwe-laser ye-UV ngamandla abalulekileyo kwimarike yokucutshungulwa kwe-laser. Ngokuthandwa kwe-laser ze-UV zasekhaya, ukhuphiswano phakathi kweempawu zasekhaya kunye neempawu zangaphandle luya kuphucuka, nto leyo eyenza ii-laser ze-UV zithandeke ngakumbi kwindawo yokucutshungulwa kwe-laser ye-UV yasekhaya.
Eyona ndlela iphambili yee-laser ze-UV ibandakanya uyilo lwe-resonant cavity, ulawulo lokuphindaphinda kwamaza, imbuyekezo yobushushu ngaphakathi kwe-cavity kunye nolawulo lokupholisa. Ngokuphathelele ulawulo lokupholisa, ii-laser ze-UV ezinamandla aphantsi zinokupholiswa zizixhobo zokupholisa amanzi kunye nezixhobo zokupholisa umoya kwaye uninzi lwabavelisi luyakwazi ukusebenzisa izixhobo zokupholisa amanzi. Ngokuphathelele ii-laser ze-UV ezinamandla aphakathi, zonke zixhotyiswe ngesixhobo sokupholisa amanzi. Ke ngoko, ukunyuka kwemfuno yemarike yee-laser ze-UV ngokuqinisekileyo kuya kunyusa imfuno yemarike yee-water chillers ezikhethekileyo kwii-UV lasers. Ukuphuma okuzinzileyo kwee-UV lasers kufuna ukuba ubushushu bangaphakathi buhlale ngaphakathi koluhlu oluthile. Ke ngoko, malunga nesiphumo sokupholisa, ukupholisa amanzi kuzinzile kwaye kuthembekile kunokupholisa umoya.
Njengoko kwaziwa ngumntu wonke, okukhona ukuguquguquka kobushushu bamanzi kwi-water chiller kukhulu (oko kukuthi ulawulo lobushushu aluchanekanga), kokukhona kuya kubakho ukuchithwa kokukhanya okungaphezulu, okuya kuchaphazela iindleko zokucubungula i-laser kwaye kunciphise ubomi be-laser. Nangona kunjalo, okukhona ubushushu be-water chiller buchanekile, kokukhona ukuguquguquka kwamanzi kuya kuba kuncinci kwaye ukuphuma kwe-laser okuzinzileyo kuya kwenzeka. Ukongeza, uxinzelelo lwamanzi oluzinzileyo lwe-water chiller lunokunciphisa kakhulu umthwalo wepayipi ye-laser kwaye luthintele ukuveliswa kwe-bubble. Ii-water chiller ze-S&A Teyu ezinoyilo oluncinci kunye noyilo olufanelekileyo lwepayipi zinokuthintela ukuveliswa kwe-bubble kwaye zigcine ukuphuma kwe-laser okuzinzileyo, okunceda ukwandisa ubomi bokusebenza kwe-laser kwaye konge iindleko kubasebenzisi.
