Silika (Si)
He uliuli-hina ke ano o ka silikon.Loaʻa iā ia ka laulā hoʻouna kiʻekiʻe o 3 - 5 µm ma luna o ka nui o ka hoʻouna ʻana o 1.2 - 8 µm.Ma muli o ka conductivity thermal kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, kūpono ia no nā aniani laser a me nā kānana optical.Hoʻohana pū ʻia nā poloka silika nui me nā ʻili i hoʻomaʻamaʻa ʻia ma ke ʻano he neutron i nā hoʻokolohua physics.He haʻahaʻa haʻahaʻa a maʻalahi ka Si, ʻoi aku ka liʻiliʻi ma mua o Ge a i ʻole ZnSe & loaʻa ka ʻano like me ke aniani optical, no laila hiki ke hoʻohana ʻia i kekahi mau kūlana kahi e hopohopo ai ke kaumaha.Manaʻo ʻia ka uhi AR no ka hapa nui o nā noi.Hoʻoulu ʻia ʻo Silicon e ka Czochralski pulling techniques (CZ) a loaʻa iā ia kekahi oxygen e hoʻoulu ai i kahi kaula absorption ikaika ma 9 µm, no laila ʻaʻole kūpono ia no ka hoʻohana ʻana me CO.2nā noi hoʻoili laser.No ka pale ʻana i kēia, hiki ke hoʻomākaukau ʻia ʻo Silicon e kahi kaʻina Float-Zone (FZ).
