Nd YAG
I hangaia i roto i nga ono tekau o te rautau kua hipa, ko Nd:YAG ko te karaihe taiaho tino whakamahia mo nga taonga karaihe toka.Ko ona tawhā taiaho he taupatupatu pai i waenga i nga kaha me nga ngoikoretanga o tana whakataetae.Nd: Kei te whakamahia nga tioata YAG ki nga momo taiaho totoka katoa.Ka whakatauritea ki etahi atu tioata taiaho, ko te roanga o te rere o te rangi he rua atu i te Nd:YVO4, he pai ake hoki te kawe waiariki.
