Nd YAG
Yahimbwe mu myaka ya za mirongo itandatu yikinyejana gishize, Nd: YAG yabayeho kandi iracyakomeza kuba lazeri ikoreshwa cyane kubintu bikomeye bya kristu.Ibipimo bya laser ni ubwumvikane bwiza hagati yimbaraga nintege nke zamarushanwa yayo.Nd: YAG kristu ikoreshwa muburyo bwose bwa lazeri ikomeye.Ugereranije nabandi ba kristu ya laser, ubuzima bwayo bwa fluorescence burenze kabiri Nd: YVO4, kandi nubushyuhe bwumuriro nabwo nibyiza.
