Opisano podstawy techniczne oraz mechanizm procesu cięcia laserowego metali i techniki cięcia laserowego w stanie ciekłym metalu szczeliny, w stanie odparowanym oraz z wykorzystaniem ciepła reakcji egzotermicznej spalania metalu szczeliny cięcia. Podano teoretyczne zależności określające wpływ mocy wiązki laserowej, współczynnika absorpcji promieniowania laserowego oraz właściwości cieplno-fizycznych ciętego metalu na prędkość cięcia.
