I-laser eqinile ephephe ngeso enobude obuphumayo obungu-1535nm.Inezici zevolumu encane, ukusetshenziswa kwamandla okuphansi, ukuthembeka okuphezulu nokuzinza okuhle, ububanzi obuhlukahlukene bokushisa, okufakazela ukuthi i-laser ephephile, ephumelelayo futhi ezinzile yamehlo.
Yamukela i-LD pumped erbium laser enobude obuyi-1.4 ~ 2.0μm beso obuphephile bokukhipha, ikhwalithi yayo yokubona iseduze nenani elilinganiselwe le-diffraction.
