Ngwa LGS (Lithium Gallium Silicate) na-ezo aka n'ụdị ihe eji eme ihe na-eto eto nke otu ihe nkiri kristal.A na-ejikarị ihe ndị LGS eme ihe n'ọhịa nke electro-optic na acousto-optic ngwaọrụ, dị ka ndị na-atụgharị ugboro ugboro, ndị na-ahụ anya modulators, n'elu ala acoustic ife ngwaọrụ, wdg.
Ngwa LGS nwere lithium, gallium, na ion silicate nwere ụdị kristal akọwapụtara.Ngwakọta a pụrụ iche na-enye LGS substrates ezigbo ngwa anya na anụ ahụ maka ngwa dị iche iche.Ngwakọta ndị a na-egosipụta indices refractive dịtụ elu, mmịnye ọkụ dị ala, yana nghọta mara mma nke a na-ahụ anya na nso ogologo ikuku infrared.
