Kule mihla, imakethi yelaser ilawulwa ziifiber lasers ezigqwesa iilaser zeUV. Usetyenziso olubanzi lwemizi-mveliso luyayithethelela inyani yokuba iifayibha lasers zenza esona sabelo sikhulu semarike. Ngokuphathelele iilaser ze-UV, zisenokungasebenzi njengeefayibha lasers kwiindawo ezininzi ngenxa yokusikelwa umda, kodwa luphawu oluthile lwe-355nm wavelength ebeka ii-lasers ze-UV zahluke kwezinye iilaser, zenza ii-lasers ze-UV zibe lukhetho lokuqala kwizicelo ezithile ezikhethekileyo.
I-laser ye-UV iphunyezwa ngokubeka ubuchule besithathu bokuvelisa i-harmonic kwisibane se-infrared. Ngumthombo wokukhanya okubandayo kwaye indlela yayo yokucubungula ibizwa ngokuba yi-cold processing. Ngobude obufutshane bobude & Ububanzi be-pulse kunye ne-high-quality beam yokukhanya, iilaser ze-UV zinokufikelela kwi-micromachining echanekileyo ngokuvelisa indawo ye-laser egxile ngakumbi kunye nokugcina eyona ndawo incinci echaphazela ubushushu. Ukufunxa amandla aphezulu e-laser ye-UV, ngakumbi ngaphakathi kuluhlu lwamaza e-UV kunye ne-pulse emfutshane, ivumela izixhobo ukuba zibe ngumphunga ngokukhawuleza ukuze kuncitshiswe uMmandla ochaphazela ubushushu kunye ne-carbonization. Ukongeza, indawo encinci yokugxila yenza ukuba ii-laser ze-UV zisetyenziswe kwindawo echanekileyo kunye nencinci yokusetyenzwa. Ngenxa yeNdawo encinci echaphazela ubushushu, ukusetyenzwa kwe-laser ye-UV kuhlelwe njengokusetyenzwa okubandayo kwaye yenye yezona zinto zibalaseleyo ze-laser ye-UV eyohlula kwezinye ii-lasers. I-laser ye-UV inokufikelela ngaphakathi kwezixhobo, kuba isebenza kwi-photochemical reaction xa kusenziwa. Ubude be-laser ye-UV bufutshane kunobude obubonakalayo. Nangona kunjalo, bububude obufutshane obuvumela iilaser ze-UV ukuba zigxininise ngokuchanekileyo ukuze ii-lasers ze-UV zikwazi ukwenza inkqubo echanekileyo yokuphela kwesiphelo kunye nokugcina ukuchaneka okumangalisayo kwendawo ngexesha elinye.
I-laser ye-UV isetyenziswa ngokubanzi ekuphawuleni i-elektroniki, ukuphawula kwi-casing yangaphandle yezixhobo zasekhaya ezimhlophe, ukumakishwa komhla wokuvelisa ukutya. & iyeza, isikhumba, umsebenzi wezandla, ukusika ilaphu, imveliso yerabha, izinto zeglasi, i-nameplate, izixhobo zonxibelelwano njalo njalo. Ukongeza, iilaser ze-UV zinokufakwa kwiindawo eziphezulu kunye nezichanekileyo zokusetyenzwa, njengokusika kwePCB kunye nokugrumba iikeramics. & ukubhala. Kufanelekile ukukhankanya ukuba i-EUV kuphela kwendlela yokucutshungulwa kwelaser ekwaziyo ukwenza kwi-7nm chip kwaye ubukho bayo benza ukuba uMthetho kaMoore uhlale kude kube namhlanje.
Kwiminyaka emibini edlulileyo, imakethi ye-UV laser ifumene uphuhliso olukhawulezayo. Phambi kowama-2016, uthutho lulonke lwasekhaya lweelaser ze-UV lwalungaphantsi kweeyunithi ezingama-3000. Nangona kunjalo, ngo-2016, eli nani liye lanyuka laya kwiiyunithi ezingaphezu kwe-6000 ngokumangalisayo kwaye ngo-2017, inani laxhuma kwiiyunithi ze-9000. Uphuhliso olukhawulezayo lwemakethi ye-laser ye-UV isiphumo sokunyuka kwemfuno yentengiso ye-UV laser high-end processing application. Ukongeza, ezinye ii-applications ebezilawulwa zii-laser ze-YAG kunye ne-CO2 lasers ngaphambili ngoku zithathelwe indawo zii-laser ze-UV.
Zininzi kakhulu iinkampani zasekhaya ezivelisa kwaye zithengise iilaser zeUV, kubandakanya iHuaray, Inngu, Bellin, Logan, Maiman, RFH, Inno, DZD Photonics kunye neFotonix. Emuva ngo-2009, ubuchule belaser ye-UV yasekhaya yayikwinqanaba lokuqala lophuhliso, kodwa ngoku sele ikhulile. Uninzi lweenkampani ze-laser ze-UV ziye zakuqonda ukuveliswa kobuninzi, okuphula ulawulo lweempawu zangaphandle kwii-lasers ze-UV eziqinileyo kunye nokunciphisa kakhulu ixabiso le-lasers ze-UV zasekhaya. Ixabiso elincitshisiweyo kakhulu likhokelela ekuthandeni ngakumbi ukusetyenzwa kwe-laser ye-UV, enceda ekuphuculeni umgangatho wokucubungula wasekhaya. Nangona kunjalo, kufanelekile ukukhankanya ukuba abavelisi basekhaya bagxile ikakhulu kumandla aphakathi asezantsi iilaser ze-UV ukusuka kwi-1W-12W. (I-Huaray iphuhlise i-lasers ye-UV engaphezulu kwe-20W.) Ngelixa kumandla aphezulu e-UV lasers, abavelisi basekhaya abasakwazi ukuvelisa, beshiya ngasemva kweempawu zangaphandle.
Ngokubhekiselele kwiimpawu zangaphandle, iSpectral-Physics, Coherent, Trumpf, AOC, Powerlase kunye ne-IPG ngabona badlali baphambili kwiimarike ze-laser ze-UV zaphesheya. I-Spectral-Physics iphuhlise i-60W yamandla aphezulu e-UV lasers (M2 <1.3) ngelixa i-Powerlase ine-DPSS 180W UV lasers (M2<30). Ngokuphathelele i-IPG, umthamo wayo wokuthengisa wonyaka ufikelela phantse kwizigidi ezilishumi zee-RMB kwaye i-fiber laser akhawunti yayo ingaphezulu kwe-50% yesabelo semalike yemarike ye-fiber laser yaseTshayina. Nangona umthamo wentengiso wee-lasers ze-UV e-China uthatha isahlulo esincinci kwixabiso layo elipheleleyo lokuthengisa xa kuthelekiswa ne-fiber lasers, i-IPG isacinga ukuba ii-lasers ze-UV zaseTshayina ziya kuba nekamva elithembisayo, elixhaswa kukwanda kwemfuno yokusetyenzwa kwezixhobo zombane zabathengi e-China. Kwikota edlulileyo, i-IPG ithengise i-laser ye-UV engaphezulu kwe-1 yezigidi zeedola zaseMelika. IPG inethemba lokukhuphisana neSpectral-Physics eyi-subsidiary ye-MKS kulo mmandla kunye ne-DPSSL yemveli ngakumbi.
Ngokubanzi, nangona iilaser ze-UV zingadumanga njengee-laser ze-fiber, iilaser ze-UV zisenekamva elithembisayo kwizicelo nakwiimfuno zentengiso, ezinokubonwa ekonyukeni okumangalisayo komthamo wothutho kule minyaka mi-2 idlulileyo. Ukusetyenzwa kwe-laser ye-UV ngamandla abalulekileyo kwimarike yokusetyenzwa kwe-laser. Ngokuthandwa kwee-lasers ze-UV zasekhaya, ukhuphiswano phakathi kweempawu zasekhaya kunye neempawu zangaphandle luya kukhula, nto leyo eyenza ukuba iilaser ze-UV zidume ngakumbi kwindawo yokusetyenzwa kwe-laser ye-UV yasekhaya.
Obona buchule buphambili beelaser ze-UV bubandakanya uyilo lombhobho ophinda-phindayo, ulawulo lokuphindaphinda amaza, imbuyekezo yobushushu bomgodi ongaphakathi kunye nolawulo lokupholisa. Ngokubhekiselele kulawulo lokupholisa, iilaser zamandla aphantsi e-UV zinokupholiswa ngezixhobo zokupholisa amanzi kunye nezixhobo zokupholisa umoya kwaye uninzi lwabavelisi bakulungele ukusebenzisa izixhobo zokupholisa amanzi. Ngokubhekiselele kwi-laser ye-UV yamandla aphakathi aphezulu, zonke zixhotyiswe ngesixhobo sokupholisa amanzi. Ke ngoko, ukwanda kwemfuno yentengiso yee-lasers ze-UV ngokuqinisekileyo kuya konyusa imfuno yentengiso yee-chillers zamanzi ezikhethekileyo kwii-lasers ze-UV. Imveliso ezinzileyo ye-lasers ye-UV idinga ukushisa kwangaphakathi ukugcina ngaphakathi koluhlu oluthile. Ngoko ke, ngokubhekiselele kwisiphumo sokupholisa, ukupholisa kwamanzi kuzinzile kwaye kunokwethenjelwa ngakumbi kunokupholisa umoya.
Njengoko kusaziwa kubo bonke, okukhulu ukuguquguquka kobushushu bamanzi kwi-chiller yamanzi (okt ulawulo lwamaqondo obushushu aluchanekanga), kokukhona inkcitho yokukhanya iya kwenzeka, eya kuchaphazela iindleko zokusetyenzwa kwelaser kunye nokunciphisa ixesha lokuphila kweelasesi. Nangona kunjalo, okukhona uchaneke ngakumbi ubushushu be-chiller yamanzi, kokukhona kuya kuba kuncinci ukuguquguquka kwamanzi kunye nokuphuma kwelaser kuzinzile kuya kwenzeka. Ukongezelela, uxinzelelo lwamanzi oluzinzile lwe-chiller yamanzi lunokunciphisa kakhulu umthwalo wombhobho we-lasers kwaye ugweme ukuveliswa kwe-bubble. S&I-chillers yamanzi ye-Teyu enoyilo oludibeneyo kunye noyilo olufanelekileyo lombhobho unokuphepha ukuveliswa kwe-bubble kunye nokugcina imveliso ye-laser ezinzileyo, enceda ukwandisa ubomi bokusebenza kwee-lasers kunye nokugcina iindleko kubasebenzisi.
GUANGZHOU TEYU ELECTROMECHANICAL CO., LTD. (ekwabizwa ngokuba yi-S&I-Teyu chiller) iphuhlise i-chiller yamanzi eyilelwe ngokukodwa ukupholisa i-3W-15W UV laser. Ibonakala ngolawulo oluchanekileyo lobushushu (±0.3°C uzinzo) kunye nokusebenza okupholileyo okuzinzileyo kunye neendlela ezimbini zokulawula ubushushu, kubandakanywa imo yokulawula ubushushu obuqhubekayo kunye nemo yokulawula ubushushu obukrelekrele. Ngoyilo oludibeneyo, kulula ukuhanjiswa. Ukongezelela, ixhotywe ngenguqu yokulawula imveliso kwaye inemisebenzi yokukhusela i-alamu, njenge-alamu yokuhamba kwamanzi kunye ne-alamu ye-ultra-high / ephantsi. Ukuthelekisa neempawu ezifanayo, uS&Izikhenkcezisi zamanzi zaseTeyu zizinzile ngakumbi ekusebenzeni kokupholisa.
