umshini wokusika nge-laser

I-Laser uhlobo lokukhanya, njengokukhanya kwayo kwe-electroluminescence ngokwemvelo, olukhiqizwa yizinguquko ze-athomu (ama-molecule noma ama-ionic) futhi lubangelwa imisebe ezenzakalelayo. Nakuba i-laser ilula, kodwa kusobala ukuthi ihlukile ekukhanyeni okuvamile ukuthi i-laser ithembele kuphela emisebeni ezenzakalelayo isikhathi esifushane kakhulu ekuqaleni, futhi inqubo ngemva kwalokho inqunywa ngokuphelele yimisebe ejabulisayo, ngakho-ke i-laser inombala omsulwa kakhulu, cishe ayikho isiqondiso sokuhluka, umshini wokuqopha, ukuqina okuphezulu kakhulu okukhanyayo. Ngesikhathi esifanayo, i-laser inokuhambisana okuphezulu, amandla aphezulu, isiqondiso esiphezulu, i-laser idluliselwa yi-reflector ngemva kokuba i-laser ikhiqizwe futhi ikhanyiswe ezimpahleni ezicutshunguliwe ngesibuko sokuhlanganisa, ukuze izimpahla ezicutshunguliwe (ubuso) zitholwe amandla okushisa aqinile futhi izinga lokushisa likhuphuke kakhulu, ukuze iphuzu lincibilike ngokushesha noma lishiswe ngenxa yokushisa okuphezulu, futhi ithrekhi egijimayo yekhanda le-laser isetshenziselwa ukufeza injongo yokucubungula.
