Nd YAG
Hana ʻia i nā makahiki kanaono o ke kenekulia i hala, ʻo Nd:YAG ka mea i hoʻohana nui ʻia i ka kristal laser i hoʻohana nui ʻia no nā mea aniani paʻa.ʻO kāna mau ʻāpana laser kahi hoʻohālikelike maikaʻi ma waena o nā ikaika a me nā nāwaliwali o kāna hoʻokūkū.Nd: Hoʻohana ʻia nā kristal YAG i nā ʻano lasers solid-state.Ke hoʻohālikelike ʻia me nā kristal laser ʻē aʻe, ʻelua ʻoi aku kona ola fluorescence ma mua o Nd: YVO4, a ʻoi aku ka maikaʻi o ka conductivity thermal.

★ Haʻahaʻa Pohō ma 1064 nm, Kiʻekiʻe Optical Quality , Mea Mechanical maikaʻi a me Thermal
★ Loaʻa kiʻekiʻe, paepae haʻahaʻa, hana kiʻekiʻe
★ Ma muli o ka hoʻohālikelike cubic a me ke ʻano kiʻekiʻe, Nd:YAG maʻalahi ke hana me ke ʻano TEM00
★ E hana i ka laser polū me ka pinepine-pālua o 946nm
★ E hoʻololi pololei me Cr:YAG
★ E hana ʻia i kahi laser mana kiʻekiʻe a hiki i ka pae KW
