Ubuchwepheshe bokuhlanza i-laser busebenzisa ububanzi obuncane be-pulse, ama-lasers anamandla aphezulu phezu kwento ezohlanzwa.Ngemiphumela ehlanganisiwe yokudlidliza okusheshayo, ukuhwamuka, ukubola, nokuxebuka kwe-plasma, ukungcola, amabala okugqwala, noma ama-coating angaphezulu ahwamuka futhi ahlukaniswe, kufezwe ukuhlanzwa kwendawo.
Ukuhlanzwa nge-laser kunikeza izinzuzo ezifana nokungathintani, ukuvumela imvelo, ukunemba okuphumelelayo, futhi akukho monakalo ku-substrate, okuyenza isebenze ezimeni ezihlukahlukene.
Laser Cleaning
Okuluhlaza futhi Okuphumelelayo
Imboni yamasondo, imboni yamandla amasha, nemboni yemishini yokwakha, phakathi kokunye, isebenzisa kabanzi ukuhlanzwa kwe-laser.Esikhathini semigomo "yekhabhoni embaxambili", ukuhlanzwa nge-laser kuvela njengesixazululo esisha emakethe yokuhlanza yendabuko ngenxa yokusebenza kahle kwayo okuphezulu, ukulawuleka okunembayo, nezici ezihambisana nemvelo.
Umqondo wokuhlanza i-Laser:
Ukuhlanza i-laser kuhilela ukugxilisa imishayo ye-laser endaweni ebonakalayo ukuze ihwamuke ngokushesha noma ikhiphe ukungcola okungaphezulu, kuzuzwe ukuhlanzwa kwezinto ezibonakalayo.Uma kuqhathaniswa nezindlela ezihlukahlukene zendabuko zokuhlanza umzimba noma amakhemikhali, ukuhlanzwa kwe-laser kubonakala ngokungathinteki, akukho okusebenzisekayo, akukho ukungcola, ukunemba okuphezulu, kanye nomonakalo omncane noma ongekho, okwenza kube yisinqumo esihle esizukulwaneni esisha sobuchwepheshe bokuhlanza izimboni.
Isimiso sokuhlanza i-Laser:
Umgomo wokuhlanza nge-laser uyinkimbinkimbi futhi ungabandakanya kokubili izinqubo zomzimba nezamakhemikhali.Ezimweni eziningi, izinqubo zomzimba zibusa, zihambisana nokusabela kwamakhemikhali ingxenye.Izinqubo eziyinhloko zingahlukaniswa ngezinhlobo ezintathu: inqubo yokukhipha umoya, inqubo yokushaqeka, nenqubo ye-oscillation.
Inqubo yokufakwa kwegesi:
Lapho i-laser irradiation enamandla amakhulu isetshenziswa ebusweni bento, indawo engaphezulu idonsa amandla e-laser futhi iwaguqule abe amandla angaphakathi, okwenza izinga lokushisa elingaphezulu likhuphuke ngokushesha.Lokhu kukhuphuka kwezinga lokushisa kufinyelela noma kudlule izinga lokushisa lokuhwamuka kwempahla, okubangela ukuthi ukungcola kuphume endaweni ebonakalayo ngesimo somhwamuko.Ukuhwamuka okukhethiwe kuvame ukwenzeka lapho izinga lokumuncwa kokungcola ku-laser liphezulu kakhulu kunalelo le-substrate.Isibonelo esijwayelekile sohlelo ukuhlanzwa kokungcola ezindaweni zamatshe.Njengoba kuboniswe kumdwebo ongezansi, ukungcola endaweni yetshe kudonsa kakhulu i-laser bese kuhwamuka ngokushesha.Uma ukungcola sekususwe ngokuphelele, futhi i-laser ikhipha ukukhanya kwetshe, ukumuncwa kuba buthakathaka, futhi amandla e-laser engeziwe ahlakazeka ebusweni betshe.Ngenxa yalokho, kunoshintsho oluncane ekushiseni kwendawo engaphezulu kwamatshe, ngaleyo ndlela ivikeleke emonakalweni.
Inqubo evamile ngokuyinhloko ehilela isenzo samakhemikhali yenzeka lapho kuhlanzwa ukungcola kwezinto eziphilayo ngamalaser e-ultraviolet wavelength, inqubo eyaziwa ngokuthi ukukhishwa kwe-laser.Ama-laser e-Ultraviolet anamaza amaza amafushane namandla e-photon aphezulu.Isibonelo, i-laser ye-KrF excimer ene-wavelength engu-248 nm inamandla e-photon angu-5 eV, aphakeme ngokuphindwe izikhathi ezingu-40 kunalawo e-CO2 laser photons (0.12 eV).Amandla e-photon aphezulu kangaka anele ukunqamula izibopho zamangqamuzana ezintweni eziphilayo, okubangela ukuthi i-CC, CH, CO, njll., amabhondi kukungcola kwe-organic aphuke lapho emunca amandla e-photon we-laser, okuholela ekugayweni kwe-pyrolytic nokususwa phezulu.
Inqubo yokushaqeka ekuhlanzeni i-Laser:
Inqubo yokushaqeka ekuhlanzweni nge-laser ibandakanya uchungechunge lokusabela okwenzeka ngesikhathi sokusebenzelana phakathi kwe-laser nokokusebenza, okuholela kumagagasi okwethuka anomthelela ongaphezulu kokokusebenza.Ngaphansi kwethonya lala maza ashaqisayo, ukungcola okungaphezulu kuyaphahlazeka kube uthuli noma izingcezu, kuxebuka kude.Izindlela ezibangela lawa maza okushaqeka ziyahlukahluka, okuhlanganisa iplasma, umhwamuko, nokwanda okusheshayo kokushisa kanye nezimo zokufinyela.
Ukuthatha amagagasi okwethuka kwe-plasma njengesibonelo, singaqonda kafushane ukuthi inqubo yokushaqeka ekuhlanzeni kwe-laser isusa kanjani ukungcola okungaphezulu.Ngokusetshenziswa kwamalases we-ultra-short pulse wide (ns) namandla aphezulu aphezulu (107– 1010 W／cm2), izinga lokushisa elingaphezulu lingakhuphuka ngokucijile lifinyelele emazingeni okushisa okuhwamuka ngisho noma ukumuncwa okungaphezulu kwe-laser kubuthaka.Lokhu kwenyuka kwezinga lokushisa kwakha umhwamuko ngaphezu kobuso bento, njengoba kuboniswe emfanekisweni (a).Izinga lokushisa lomhwamuko lingafinyelela ku-104 - 105 K, okwanele ukwenza i-ionize umhwamuko ngokwawo noma umoya ozungezile, wakhe iplasma.I-plasma ivimba i-laser ukuthi ingafinyeleli endaweni ebonakalayo, mhlawumbe imise ukuhwamuka komhlaba.Kodwa-ke, i-plasma iyaqhubeka nokumunca amandla e-laser, ikhulise izinga lokushisa layo futhi idale isimo sasendaweni sokushisa okuphezulu kakhulu nokucindezela.Lokhu kudala umthelela wesikhashana we-1-100 kbar endaweni ebonakalayo futhi idlulisela kancane kancane ngaphakathi, njengoba kuboniswe emifanekisweni (b) kanye (c).Ngaphansi komthelela wegagasi lokwethuka, ukungcola okungaphezulu kuphuka kube uthuli oluncane, izinhlayiya, noma izingcezu.Lapho i-laser isuka endaweni ene-radiated, i-plasma iyanyamalala ngokushesha, idale ukucindezela okungalungile kwendawo, futhi izinhlayiya noma izingcezu zokungcola ziyasuswa ebusweni, njengoba kuboniswe emfanekisweni (d).
Inqubo ye-Oscillation ku-Laser Cleaning:
Enqubweni ye-oscillation yokuhlanza nge-laser, kokubili ukushisa nokupholisa kwempahla kwenzeka ngokushesha okukhulu ngaphansi kwethonya lama-laser we-short-pulse.Ngenxa yama-coefficients ahlukene okunweba okushisayo kwezinto ezihlukahlukene, ukungcola okungaphezulu kanye ne-substrate kunwetshwa imvamisa ephezulu yokushisa kanye nokufinyela kwamazinga ahlukahlukene uma kuvezwe kukukhanya kwe-laser ye-short-pulse.Lokhu kuholela kumphumela we-oscillatory obangela ukuthi ukungcola kukhishwe ebusweni bezinto ezibonakalayo.
Ngalesi nqubo yokucwecwa, ukuhwamuka kwezinto kungase kungenzeki, futhi i-plasma ayakheka ngempela.Esikhundleni salokho, inqubo incike emandleni okugunda akhiqizwe kusixhumanisi phakathi kokungcola kanye ne-substrate ngaphansi kwesenzo se-oscillatory, esiphula isibopho phakathi kwabo.Ucwaningo lubonise ukuthi ukukhulisa kancane i-engeli yesigameko se-laser kungathuthukisa ukuxhumana phakathi kwe-laser, ukungcola okuyizinhlayiyana, kanye nesixhumi esibonakalayo se-substrate.Le ndlela yehlisa umkhawulo wokuhlanza nge-laser, okwenza umphumela we-oscillatory ubonakale kakhudlwana futhi uthuthukise ukusebenza kahle kokuhlanza.Kodwa-ke, i-engeli yesigameko akufanele ibe nkulu kakhulu, njengoba i-engeli ephakeme kakhulu inganciphisa ukuminyana kwamandla okusebenza endaweni ebonakalayo, ngaleyo ndlela yenze buthaka ikhono lokuhlanza le-laser.
