I-laser ye-UV ngokusebenza okuphezulu kancane kancane kuba umkhuba omusha wemakethe
Ilaser ye-UV iwuhlobo lwe-laser ene-wavelength engu-355nm.Ngenxa yobude bayo obufushane beza nobubanzi be-pulse obuncane, i-UV laser ingakhiqiza indawo encane kakhulu okugxilwe kuyo futhi igcine indawo encane ethinta ukushisa. Ngakho-ke, kubizwa nangokuthi “ukucubungula okubandayo”. Lezi zici zenza i-UV laser ikwazi ukwenza ukucubungula okunembe kakhulu ngenkathi igwema ukuwohloka kwezinto
Kulezi zinsuku, njengoba izinhlelo zokusebenza zezimboni zidinga kakhulu ekusebenzeni kahle kwe-laser, i-10W+ nanosecond UV laser ikhethwa abantu abaningi ngokwengeziwe. Ngakho-ke, kubakhiqizi be-laser ye-UV, ukuthuthukisa amandla aphezulu, i-pulse emincane, imvamisa ephezulu yokuphindaphinda amandla aphakathi nendawo ephezulu ye-nanosecond UV laser kuzoba umgomo oyinhloko wokuncintisana emakethe.
I-UV laser ibona ukucutshungulwa ngokucekela phansi ngokuqondile amabhondi amakhemikhali axhuma izinto’s izingxenye ze-athomu. Le nqubo ayiwinanga’ ukushisa okuzungezile, ngakho iwuhlobo “kubanda” inqubo. Ukwengeza, izinto eziningi ezisetshenziswayo zingakwazi ukumunca ukukhanya kwe-ultraviolet, ngakho-ke i-UV laser ingakwazi ukucubungula izinto i-infrared noma eminye imithombo ye-laser ebonakalayo engakwazi’t. I-laser ye-UV enamandla amakhulu isetshenziswa kakhulu ezimakethe ezisezingeni eliphezulu ezidinga ukucutshungulwa okunembayo okuphezulu, okuhlanganisa ukubhola/ukusikwa kwe-FPCB ne-PCB, ukubhola/ukubhala izinto zobumba, ukusika ingilazi/isafire, ukusika isinkwa esilucwecwana sengilazi ekhethekile nokumaka nge-laser.
Kusukela ngo-2016, imakethe ye-laser ye-UV yasekhaya ikhula ngokushesha. Trumf, Coherent,Spectra-Physics nezinye izinkampani zakwamanye amazwe zisathatha imakethe esezingeni eliphezulu. Ngokuqondene nemikhiqizo yasekhaya, i-Huaray, i-Bellin, i-Inngu, i-RFH, i-Inno, i-akhawunti ye-Gain Laser i-akhawunti engu-90% yesabelo semakethe emakethe yasekhaya ye-UV laser.
Ukuxhumana kwe-5G kuletha ithuba lokusebenzisa i-laser
Amazwe amakhulu emhlabeni wonke afuna ubuchwepheshe obuthuthuke kakhulu njengendawo entsha yokuthuthukiswa. Futhi i-China inobuchwepheshe obuhamba phambili be-5G obungakwazi ukuncintisana namazwe ase-Europe, i-US naseJapane. Unyaka ka-2019 bekuwunyaka wokuthengiswa kwasekhaya kwangaphambili kobuchwepheshe be-5G futhi kulo nyaka ubuchwepheshe be-5G sebuvele balethe amandla amaningi ku-electronics abathengi.
Namuhla, iChina inabasebenzisi bomakhalekhukhwini abangaphezu kwebhiliyoni futhi isingene enkathini yama-smart phone. Uma sibheka emuva ukuthuthukiswa kwe-smart phone e-China, isikhathi esikhula ngokushesha singo-2010-2015. Ngalesi sikhathi, isignali yokuxhumana ithuthukiswe kusuka ku-2G kuya ku-3G kanye ne-4G futhi manje i-5G kanye nesidingo samafoni ahlakaniphile, amaphilisi, imikhiqizo egqokekayo yayikhula, okwaletha ithuba elihle embonini yokucubungula i-laser. Ngaleso sikhathi, isidingo selaser ye-UV kanye ne-ultra-fast laser nayo iyanda
I-Ultra-short pulsed UV laser ingaba ithrendi yesikhathi esizayo
Ngokwe-spectrum, i-laser ingahlukaniswa nge-laser ye-infrared, i-laser eluhlaza, i-UV laser kanye ne-blue laser. Ngesikhathi sokushaya kwenhliziyo, i-laser ingahlukaniswa ibe i-microsecond laser, nanosecond laser, picosecond laser kanye ne-femtosecond laser. I-laser ye-UV itholakala ngesizukulwane sesithathu se-harmonic se-laser ye-infrared, ngakho-ke kubiza kakhulu futhi kuyinkimbinkimbi kakhulu. Namuhla, ubuchwepheshe belaser ye-nanosecond UV yabakhiqizi be-laser basekhaya sebevele bavuthiwe futhi imakethe ye-laser ye-UV engu-2-20W nanosecond ithathwa ngokuphelele ngabakhiqizi basekhaya. Eminyakeni emibili edlule, imakethe ye-laser ye-UV ibinokuncintisana kakhulu, ngakho intengo iba phansi, okwenza abantu abaningi babone izinzuzo zokucutshungulwa kwe-UV laser. Ngokufanayo ne-laser ye-infrared, i-laser ye-UV njengomthombo wokushisa wokucutshungulwa okunembayo okuphezulu inezitayela ezimbili zokuthuthuka: amandla aphezulu kanye ne-pulse emfushane.
Ilaser ye-UV ithumela imfuneko entsha ohlelweni lokupholisa amanzi
Emkhiqizweni wangempela, ukuzinza kwamandla kanye nokuzinza kwe-pulse ye-laser ye-UV kufuna kakhulu. Ngakho-ke, KUFANELE ukuhlomisa ngesistimu yokupholisa amanzi ethembeke kakhulu. Okwamanje, amalaser amaningi angu-3W+ UV afakwe amasistimu okupholisa amanzi ukuze aqinisekise ukuthi i-laser ye-UV inokulawula okunembile kwezinga lokushisa. Njengoba i-nanosecond UV laser isengumdlali omkhulu emakethe ye-laser ye-UV, isidingo sohlelo lokupholisa amanzi sizoqhubeka nokukhula.
Njengomhlinzeki wesixazululo sokupholisa nge-laser, u-S&I-Teyu iphromothe izibandisi zokupholisa amanzi ezidizayinelwe ngokukhethekile i-UV laser eminyakeni embalwa edlule futhi ithatha isabelo semakethe esikhulu kakhulu ekusetshenzisweni kwesiqandisi kwelaser ye-UV ye-UV nanosecond. Uchungechunge lwe-RUMP, CWUL kanye ne-CWUP oluzungeza kabusha ama-laser abandayo e-UV aqashelwa kahle abasebenzisi abavela kuwo wonke umhlaba.
