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 mea haʻahaʻa a me ka māmā ʻo Si, ʻoi aku ka liʻiliʻi ma mua o Ge a i ʻole ZnSe & loaʻa ka ʻano like me ke aniani aniani, no laila hiki ke hoʻohana ʻia i kekahi mau kūlana e hopohopo ai ke kaumaha. Paipai ʻia ka uhi AR no ka hapa nui o nā noi. Hoʻoulu ʻia ʻo Silicon e ka Czochralski pulling techniques (CZ) a loaʻa 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).

Kiʻikuhi
ʻO ka pakuhi ʻākau ka pihi hoʻouna o 10 mm mānoanoa, ʻaʻole i uhi ʻia ʻo Si substrate
No ka ʻikepili kikoʻī hou aku, e ʻoluʻolu e nānā i kā mākou papa inoa optics e ʻike i kā mākou koho piha o nā optics i hana ʻia mai ke silika.
