LEYOUNGUkusika nge-laser kusebenzisa umsebe we-laser onamandla aminyene endaweni encane ukuze into esikwayo incibilike ngokushesha, ihwamuke noma ifinyelele ezingeni lokuvutha. Ngesikhathi esifanayo, umoya ogeleza ngesivinini esikhulu ulandela i-eksisi yomsebe, uphephule into encibilikile ukuze kwakheke umsiko. Inqubo ihlanganisa ukuncibilika nokuhwamuka. Indawo yophawu lokuqala yenziwa ngamandla e-laser. Endaweni yophawu lwesibili, insimbi encibilikile engenhla isebenza njengomthombo wokushisa, kusize nokuvutha kwesibili okubangelwa ukusabela komoya-mpilo. Le ndlela isika ngokushesha, ngokunemba nangekhwalithi enhle, ngokuguquka okuncane kwengxenye ecutshungulwayo. Yonke inqubo ingalawulwa ngezinombolo futhi ukusika kwenzeka kungathintani nengxenye, okugwema ukuguga kwamathuluzi.
Ukusika nge-laser kusetshenziswa ezintweni eziningi, kuhlanganise amashidi ensimbi, ipulasitiki, ingilazi, izinto zobumba, ama-semiconductor, izindwangu, ukhuni nephepha. Kusukela kwaqala ukusetshenziswa ekusikeni ngeminyaka yawo-1970s, lobu buchwepheshe sebuyingxenye ebalulekile yokukhiqiza kwezimboni zesimanje. Amagesi asetshenziswayo afaka umoya-mpilo, i-nitrogen nomoya. Ukukhetha igesi kuncika entweni esikwayo. Umoya-mpilo usetshenziswa ikakhulu emapuletini ensimbi yekhabhoni. I-nitrogen ilungele amapuleti ensimbi engagqwali, engxubevange ye-aluminium, ambozwe nge-zinc, enziwe nge-brass nezinye izinto. Kwezinye izimo kungasetshenziswa umoya, ngemva kokwelashwa kwawo maqondana namanzi namafutha.
Izinhlobo zokusika nge-laser zifaka ukusika ngokuqhekeza okulawulwayo nokusika ngokuncibilikisa nge-laser. Kweyokuqala, kushiswa izingxenye ezincane zento ephuka kalula, kudaleke umehluko wamazinga okushisa nokuguquka okukhulu kwesimo sayo, bese kuvela imifantu. Kweyesibili, i-laser incibilikisa insimbi. Umbhobho oqondaniswe ne-eksisi yomsebe ufutha igesi engabangeli i-oxidation ukuze ikhiphe insimbi encibilikile, kushiyeke umsele wokusika. Kukhona nokusika ngomoya ocindezelwe nokusika okusizwa yi-plasma. Kule ndlela yokugcina, uma amapharamitha efanele, ifu le-plasma limunca amandla e-laser ye-CO2 liwadlulisele engxenyeni ecutshungulwayo. Lokhu kuyincibilikisa ngokushesha futhi kwenyuse isivinini sokusika.
