He aha ka meaʻOkiuma Holmiumi hoʻohana ʻia no?
ʻOkiuma holmiumʻo ia kekahi o nā mea hoʻoluʻu i hoʻohana ʻia no ka cubic zirconia a me ke aniani, ma ke ʻano he kūlana calibration no nā spectrophotometers optical, ma ke ʻano he mea hoʻoulu kūikawā, phosphor a me kahi mea laser, e hāʻawi ana i ka waihoʻoluʻu melemele a ʻulaʻula paha. Hoʻohana ʻia ia i ka hana ʻana i nā aniani kala kūikawā. ʻO ke aniani e loaʻa ana ka holmium oxide a me nā hoʻonā holmium oxide he moʻo o nā piko absorption optical ʻoi i ka laulā spectral i ʻike ʻia. E like me ka hapa nui o nā oxides ʻē aʻe o nā mea honua laha ʻole, hoʻohana ʻia ka holmium oxide ma ke ʻano he mea hoʻoulu kūikawā, phosphor a me kahi mea laser. Hana ka laser Holmium ma ka nalu o kahi 2.08 micrometres, ma ke ʻano pulsed a i ʻole ka hoʻomau. Palekana kēia laser i ka maka a hoʻohana ʻia i ka lāʻau lapaʻau, nā lidars, nā ana wikiwiki o ka makani a me ka nānā ʻana i ka lewa. Hiki iā Holmium ke omo i nā neutrons fission-bred, hoʻohana ʻia hoʻi i nā reactors nuklea e mālama i ka hopena kaulahao atomika mai ka holo ʻana ma waho o ka mana.
