Laser tu thiab tshem tawm cov xeb xeb yog qhov txheej txheem zoo rau tu cov hlau. Thaum lub teeb meem laser yog shone ntawm lub hlau ntawm kev siv hauv qab nws cov ablation threshold, lub zog ntawm txoj kab teeb laser yog dispersed li thaum tshav kub tab sis nws tsis muaj cov nyhuv ntawm cov hlau.
Tag nrho cov ntaub ntawv muaj cov cwj pwm uas txheeb xyuas lawv tus cwj pwm raws li tej yam kev mob. Txhua leej txhua tus paub txog qhov taw tes melting, ntom nti, zas, hluavtaws xob. Cov yam ntxwv tsis tshua paub txog hlau yog lawv cov khoom noj tshab ablation.
Xeb, xim, varnishes thiab lwm yam kab mob muaj tag nrho ablation threshold hauv qab ntawm feem ntau cov hlau.
Ib qho yooj yim yuav ua rau lub laser tsis yooj yim kom cov kev siv ntawm lub laub nqaj yog qhov saum toj ntawm lub tsho ablation ntawm cov khoom paug, tiam sis qhov hauv qab ntawm cov hlau yuav raug ntxuav. Tshaj tawm hauv kev tshem tawm cov kab mob tsis muaj kev cuam tshuam cov hauv paus hlau txhua txoj kev.
Muaj ntau daim ntawv tso cai, tshwj xeeb tshaj yog rau cov txheej ntawm cov xim tha xim. Tab sis qhov kev tshwm sim muaj txiaj ntsig zoo ntawm kev siv zog.
