LEYOUNGUkusika ngelaser kusebenzisa umqadi wamandla axineneyo ukuze imathiriyeli inyibilike, ibe ngumphunga okanye ifikelele kubushushu bokutsha ngokukhawuleza. Umoya onesantya esiphezulu olandela i-axis yomqadi ususa izinto ezinyibilikisiweyo, nto leyo esika imathiriyeli. Le nkqubo idibanisa ukunyibilika nokujika kube ngumphunga. Indawo yokuqala yenziwa ngamandla elaser, ize eyesibini isebenze ngobushushu bentsimbi enyibilikisiweyo engaphezulu nangokusabela kwesibini kokutsha ngeoksijini. Le ndlela inika ukusika okusemgangathweni, okukhawulezayo nokuchanekileyo, kwaye icandelo ligqwethwa kancinane. Yonke inkqubo inokulawulwa ngamanani. Isixhobo asichukumisi icandelo, nto leyo ethintela ukuguga kwaso.
Ukusika ngelaser kusetyenziselwa amacwecwe esinyithi, iplastiki, iglasi, iiseramikhi, ii-semiconductor, amalaphu, umthi, iphepha nezinye izinto. Ukususela ekuqaleni kokusetyenziswa kwako ngeminyaka yoo-1970, le teknoloji yaba yinxalenye ebalulekileyo yemveliso yanamhlanje. Iigesi zokusika ziquka ioksijini, initrogen nomoya. Igesi ikhethwa ngokohlobo lwemathiriyeli. Ioksijini isetyenziselwa ikakhulu iipleyiti zentsimbi enekhabhoni, initrogen yona ilungele intsimbi engatyiwa ngumhlwa, ingxubevange yealuminiyam, iipleyiti ezigqunywe nge-zinc, iipleyiti zengxubevange yobhedu nezinye izinto. Ngamanye amaxesha kungasetyenziswa umoya, kodwa kufuneka kususwe kuwo ukufuma neoli.
Iindlela zokusika ngelaser ziquka ukusika ngokuqhekeka okulawulwayo nokusika ngokunyibilikisa. Kwindlela yokuqala, ilaser ifudumeza iindawo ezincinci zemathiriyeli eqhekeka lula. Umahluko wobushushu ubangela ukuguquka kwemilo okukhulu nokwakheka kweentanda. Kweyesibini, ilaser inyibilikisa isinyithi, ize umlomo ohambelana nomgca womqadi uvuthele igesi engaphendulisi isinyithi ngeoksijini ukuze isuse isinyithi esinyibilikileyo ize ishiye umjelo wokusika. Kukwakho ukusika ngomoya oxineneyo nokusika okuncediswa yiplasma. Xa iiparamitha zifanelekile, ilifu leplasma lifunxa amandla elaser ye-CO2 liwadlulisele kwicandelo elenziwayo, ukuze imathiriyeli inyibilike msinyane kuze kunyuke isantya sokusika.
