Ababoneleli bezixhobo zesikhenkcisi seLaser bayazuza kuphuhliso olukhawulezayo lweelaser zeUV

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, zinokungasebenzi njengee-laser zefayibha kwiindawo ezininzi ngenxa yokusikelwa umda, kodwa luphawu oluthile lwe-355nm wavelength ebeka ii-lasers ze-UV zahluke kwezinye ii-lases, zenza ii-lasers ze-UV zibe lukhetho lokuqala kuhlobo oluthile olukhethekileyo. izicelo.  

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 egxininise ngakumbi kunye nokugcina eyona ndawo incinci echaphazela ubushushu. Ukufunxa amandla aphezulu ee-laser ze-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 njengokubandayo kwaye yenye yezona zinto zibalaseleyo ze-laser ye-UV eyahlula 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 yesiphelo esiphezulu kunye nokugcina ukuchaneka okumangalisayo kwendawo ngexesha elinye.

Iilaser ze-UV zisetyenziswa 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, ezinje ngePCB yokusika kunye nokugrumba iikeramics.& ukubhala. Kufanelekile ukukhankanya ukuba i-EUV kuphela kwendlela yokucutshungulwa kwelaser ekwaziyo ukwenza kwi-chip ye-7nm kwaye ubukho bayo benza ukuba uMthetho kaMoore uhlale kude kube namhlanje.

Kwiminyaka emibini edlulileyo, imarike ye-laser ye-UV ifumene uphuhliso olukhawulezayo. Phambi kowama-2016, ukuthunyelwa okupheleleyo kwasekhaya kweelaser ze-UV zazingaphantsi 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 lwemarike ye-laser ye-UV iphuma kwimfuno eyandayo yentengiso ye-UV laser high-end processing application. Ukongeza, ezinye ii-applications ebezilawulwa ziilaser ze-YAG kunye ne-CO2 lasers ngaphambili ngoku zithathelwe indawo yi-UV lasers.

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, okwaphula ulawulo lweempawu zangaphandle kwii-lasers ze-UV eziqinileyo kunye nokunciphisa kakhulu amaxabiso ee-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 engaphezu kwe-20W.) Ngelixa i-laser ye-UV yamandla aphezulu, 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 semarike yemarike yaseTshayina yefiber laser. Nangona umthamo wentengiso yee-lasers ze-UV e-China uthatha isahlulo esincinci kumthamo wayo othengisiweyo xa uthelekisa ne-fiber lasers, i-IPG isacinga ukuba ii-lasers zase-UV zaseTshayina ziya kuba nekamva elithembisayo, elixhaswa kukwanda kwemfuno yokusetyenzwa kwezixhobo zombane zabathengi. eTshayina. Kwikota edlulileyo, i-IPG ithengise i-laser ye-UV engaphezu kwe-1 yezigidi zeedola zaseMelika. I-IPG inethemba lokukhuphisana neSpectral-Physics eyi-subsidiary ye-MKS kulo mmandla kunye neDPSSL yemveli.

Ngokubanzi, nangona iilaser ze-UV zingadumanga njengee-laser ze-fiber, iilaser ze-UV zisenekamva elithembisayo kwizicelo nakwiimfuno zentengiso, ezinokubonwa ekonyukeni okumangalisayo komthamo wokuthumela 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 kwiilaser ze-UV. Imveliso ezinzileyo ye-laser ye-UV ifuna ukushisa kwangaphakathi ukugcina ngaphakathi koluhlu oluthile. Ngoko ke, ngokubhekiselele kwimpembelelo yokupholisa, ukupholisa kwamanzi kuzinzile kwaye kunokwethenjelwa ngakumbi kunokupholisa umoya.

Njengoko kusaziwa kubo bonke, okukhona ukuguquguquka kobushushu bamanzi kwi-chiller yamanzi (o.k.t. ulawulo lobushushu aluchanekanga), kokukhona ukonakala kokukhanya kuya kwenzeka, okuya kuchaphazela iindleko zokusetyenzwa kwelaser kunye nokunciphisa ixesha lokuphila kweelases. Nangona kunjalo, okukhona uchaneke ngakumbi ubushushu be-chiller yamanzi, kokukhona kuya kuba kuncinci ukuguquguquka kwamanzi kunye nokuphuma kwelaser kuzinzile kuya kwenzeka. Ukongezelela, uxinzelelo lwamanzi oluzinzileyo lwe-chiller yamanzi lunokunciphisa kakhulu umthwalo wepayipi we-lasers kwaye ugweme ukuveliswa kwe-bubble. S&A Ii-chillers zamanzi ze-Teyu ezinoyilo oludibeneyo kunye noyilo oluchanekileyo lombhobho unokuphepha ukuveliswa kweqamu kunye nokugcina imveliso ye-laser ezinzileyo, enceda ukwandisa ubomi bokusebenza kwee-lasers kunye nokugcina iindleko kubasebenzisi.
