Ukucoca ngeLaser
Luhlaza kwaye lusebenzayo
Umzi-mveliso wamatayara, ishishini lamandla amatsha, kunye neshishini loomatshini bokwakha, phakathi kwezinye, lisebenza ngokubanzi ukucocwa kwelaser.Ngexesha leenjongo "zekhabhoni ezimbini", ukucocwa kwe-laser kuvela njengesisombululo esitsha kwimarike yemveli yokucoca ngenxa yokusebenza kwayo okuphezulu, ukulawulwa ngokuchanekileyo, kunye neempawu ezihambelana nokusingqongileyo.
Ingcamango yokuCoca iLaser:
Ukucocwa kweLaser kubandakanya ukujolisa imiqadi yelaser kumphezulu wezinto ezibonakalayo ukuba uvuthe ngokukhawuleza okanye uxobule izinto ezingcolisa umphezulu, ukuphumeza ukucocwa kwezinto ezibonakalayo.Xa kuthelekiswa neendlela ezahlukeneyo zokucoca ngokomzimba okanye iikhemikhali, ukucocwa kwe-laser kubonakaliswe ngokungabikho koqhagamshelwano, akukho zixhobo, akukho ngcoliseko, ukuchaneka okuphezulu, kunye nomonakalo omncinci okanye ongekho, okwenza kube lukhetho olufanelekileyo kwisizukulwana esitsha seteknoloji yokucoca i-industrial.
UmGaqo wokuCoca iLaser:
Umgaqo wokucoca nge-laser unzima kwaye unokubandakanya zombini iinkqubo zomzimba kunye neekhemikhali.Kwiimeko ezininzi, iinkqubo zomzimba zilawula, zihamba kunye neempendulo zemichiza.Iinkqubo eziphambili zingahlelwa zibe ziindidi ezintathu: inkqubo yokufunxa, inkqubo yomothuko, kunye nenkqubo ye-oscillation.
Inkqubo yokufakwa kwegesi:
Xa i-high-energy laser irradiation isetyenziswe kumphezulu wezinto eziphathekayo, umphezulu uthatha amandla e-laser kwaye uyiguqule ibe amandla angaphakathi, okubangela ukuba ubushushu bomhlaba bukhule ngokukhawuleza.Oku kunyuka kweqondo lobushushu kufikelela okanye kudlule ubushushu be-vaporization yezinto, kubangela ukuba ungcoliseko lususe kumphezulu wezinto ngendlela yomphunga.Umphunga okhethiweyo uhlala usenzeka xa izinga lokufunxa kwezingcolisi kwi-laser liphezulu kakhulu kunelo le-substrate.Umzekelo wesicelo esiqhelekileyo kukucocwa kokungcola kwiindawo zamatye.Njengoko kubonisiwe kulo mzobo ungezantsi, ungcoliseko kumphezulu wamatye lufunxa ngamandla i-laser kwaye lufakwe umphunga ngokukhawuleza.Emva kokuba ukungcola kususwe ngokupheleleyo, kunye ne-laser irradiates ebusweni bamatye, ukufunxa kubuthathaka, kwaye amandla amaninzi e-laser ahlakazekile ngelitye lelitye.Ngenxa yoko, kukho utshintsho oluncinci kwiqondo lokushisa lomgangatho wamatye, ngaloo ndlela ukhusela umonakalo.
Inkqubo eqhelekileyo ngokuyintloko ebandakanya isenzo sekhemikhali yenzeka xa ucoca izinto ezingcolisekileyo eziphilayo nge-ultraviolet wavelength lasers, inkqubo eyaziwa ngokuba yi-laser ablation.I-Ultraviolet lasers inobude obufutshane kunye namandla aphezulu efoton.Ngokomzekelo, i-laser ye-KrF ye-excimer laser ene-wavelength ye-248 nm inamandla e-photon ye-5 eV, ephindwe ngama-40 ngaphezu kwe-CO2 laser photons (0.12 eV).Loo mandla aphezulu efoton anele ukwaphula iibhondi zemolekyuli kwizinto eziphilayo, ezibangela ukuba i-CC, CH, CO, njl. umphezulu.
Inkqubo yokothuka kuCociso lweLaser:
Inkqubo yokothuka ekucoceni kwelaser ibandakanya uthotho lweempendulo ezenzekayo ngexesha lokusebenzisana phakathi kwelaser kunye nezinto eziphathekayo, okukhokelela kumaza othusayo achaphazela umphezulu wezinto.Phantsi kweempembelelo zala maza othusayo, izinto ezingcolisa umphezulu ziyaqhekeka zibe luthuli okanye amaqhekeza, zixobula kumphezulu.Iindlela ezibangela la maza othusayo ziyahlukahlukana, kubandakanywa iplasma, umphunga, kunye nokwandiswa kwe-thermal okukhawulezayo kunye ne-contraction phenomena.
Ukuthatha amaza othusayo e-plasma njengomzekelo, sinokuqonda ngokufutshane indlela inkqubo yokothuka ekucoceni i-laser isusa ukungcola komhlaba.Ngokusetyenziswa kwe-ultra-short pulse wide (ns) kunye ne-ultra-high peak power (107– 1010 W／cm2) lasers, ubushushu bomphezulu bunokwenyuka ngokubukhali ukuya kumaqondo obushushu bomoya nokuba ukufunxa komphezulu welaser kubuthathaka.Oku kunyuka kweqondo lobushushu ngokukhawuleza kwenza umphunga ngaphezu komphezulu wesixhobo, njengoko kubonisiwe kumzekeliso (a).Ubushushu bomphunga bunokufikelela kwi-104 - 105 K, ngokwaneleyo ukuba i-ionize umphunga ngokwawo okanye umoya ojikelezayo, wenze i-plasma.I-Plasma ivimba i-laser ekufikeleleni kumphezulu wezinto eziphathekayo, mhlawumbi imise umphunga womphezulu.Nangona kunjalo, iplasma iyaqhubeka nokufunxa amandla e-laser, inyusa ngakumbi ubushushu bayo kwaye idala imeko yendawo yobushushu obuphezulu kakhulu kunye noxinzelelo.Oku kuvelisa impembelelo yethutyana ye-1-100 kbar kumphezulu wezinto eziphathekayo kwaye ngokuqhubekayo idlulisela ngaphakathi, njengoko kubonisiwe kwimifanekiso (b) kunye (c).Phantsi kwempembelelo yomothuko, izinto ezingcolisa umphezulu ziyaqhekeka zibe luthuli oluncinci, amasuntswana, okanye amaqhekeza.Xa i-laser isuka kwindawo ene-irradiated, i-plasma iyanyamalala ngokukhawuleza, idala uxinzelelo olubi lwendawo, kwaye iinqununu okanye iziqwenga zokungcola zisuswe ebusweni, njengoko kuboniswe kumzekeliso (d).
Inkqubo ye-Oscillation kwi-Laser Cleaning:
Kwinkqubo ye-oscillation yokucoca i-laser, zombini ukufudumeza kunye nokupholisa kwezinto kwenzeka ngokukhawuleza kakhulu phantsi kweempembelelo ze-laser-pulse short.Ngenxa yee-coefficients ezahlukeneyo zokwandiswa kwe-thermal yezinto ezahlukeneyo, ukungcola komphezulu kunye ne-substrate zifumana ukwanda kwe-thermal-frequency high-frequency kunye ne-contraction ye-degrees ehlukeneyo xa ibonakaliswe kwi-short-pulse laser irradiation.Oku kukhokelela kwisiphumo se-oscillatory esibangela ukuba ukungcola kukhutshwe kwizinto eziphathekayo.
Ngexesha lenkqubo yokuxobulwa, ukukhutshwa kwezinto eziphathekayo kungenzeki, kwaye iplasma ayinakwenziwa.Kunoko, inkqubo ixhomekeke kwimikhosi ye-shear eyenziwe kwi-interface phakathi kokungcola kunye ne-substrate phantsi kwesenzo se-oscillatory, esiqhekeza ibhondi phakathi kwabo.Uphononongo lubonise ukuba ukonyusa kancinane i-engile yezehlo ze-laser kunokomeleza unxibelelwano phakathi kwe-laser, ungcoliseko oluthile, kunye nojongano lwe-substrate.Le ndlela inciphisa umda wokucocwa kwe-laser, okwenza umphumo we-oscillatory ubonakale ngakumbi kunye nokuphucula ukusebenza kakuhle kokucoca.Nangona kunjalo, i-angle yesiganeko akufanele ibe nkulu kakhulu, njengoko i-angle ephezulu kakhulu inokunciphisa ubuninzi bamandla obusebenza kumphezulu wezinto eziphathekayo, ngaloo ndlela yenza buthathaka amandla okucoca i-laser.
