I-laser ye-UV ngokusebenza okuphezulu kancane kancane kuba umkhuba omusha wemakethe
I-laser ye-UV iwuhlobo lwe-laser oluhlanganisa ubude beza beza obungu-355nm.Ngenxa yobude bayo obufushane begagasi nobubanzi be-pulse obuncane, i-UV laser ingakhiqiza indawo encane kakhulu okugxilwe kuyo futhi igcine indawo encane ethinta ukushisa. Ngakho-ke, ibizwa nangokuthi“ukucubungula okubandayo”. Lezi zici zenza i-laser ye-UV ikwazi ukwenza ukucubungula okunembe kakhulu ngenkathi igwema ukuwohloka kwezinto.
Kulezi zinsuku, njengoba izicelo zezimboni zidinga kakhulu ekusebenzeni kahle kokucubungula i-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 aphezulu i-nanosecond UV laser kuzoba umgomo oyinhloko wokuncintisana emakethe.
I-UV laser ibona ukucutshungulwa ngokucekela phansi amabhondi amakhemikhali axhuma udaba’s izingxenye ze-athomu. Lolu hlelo luphumelele’t ukushisa okuzungezile, ngakho-ke kuwuhlobo oluthile“kubanda” inqubo. Ngaphezu kwalokho, izinto eziningi zingakwazi ukumunca ukukhanya kwe-ultraviolet, ngakho-ke i-laser ye-UV ingacubungula izinto ezisetshenziswa yi-infrared noma eminye imithombo ye-laser ebonakalayo.’t inqubo. I-laser ye-UV enamandla amakhulu isetshenziswa kakhulu ezimakethe ezisezingeni eliphezulu ezidinga ukucutshungulwa okunembayo okuphezulu, okuhlanganisa ukubhola/ukusikwa kwe-FPCB ne-PCB, ukubhoboza/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-U.S. ne-Japan. Unyaka ka-2019 bekuwunyaka wokwenziwa kwasekhaya kohwebo kwasekhaya kobuchwepheshe be-5G futhi kulo nyaka ubuchwepheshe be-5G selilethe 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 yanda, okwaletha ithuba elihle embonini yokucubungula i-laser. Ngaleso sikhathi, isidingo se-laser ye-UV kanye ne-laser esheshayo futhi siyanda.
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 yi-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 wokucubungula ukunemba okuphezulu inamathrendi amabili okuthuthukisa: 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-UV laser, isidingo sohlelo lokupholisa amanzi sizoqhubeka nokukhula.
Njengomhlinzeki wesixazululo sokupholisa nge-laser, S&A U-Teyu ukhuthaze ama-chillers okupholisa amanzi aklanyelwe ngokukhethekile i-UV laser eminyakeni embalwa edlule futhi athatha isabelo semakethe esikhulu kakhulu ekusetshenzisweni kwesiqandisi kwelaser ye-UV ye-nanosecond. Uchungechunge lwe-RUMP, CWUL kanye ne-CWUP oluzungeza kabusha ama-UV laser chiller aqashelwa kahle abasebenzisi abavela kuwo wonke umhlaba.
