Mu theka lachiwiri la zaka za m'ma 1800, kupezedwa kwa kusanthula kwa spectroscopic ndi kusindikizidwa kwa matebulo a periodic, limodzi ndi kupita patsogolo kwa njira zolekanitsa ndi electrochemical za zinthu zosowa zapadziko lapansi, zinalimbikitsanso kutulukira kwa zinthu zatsopano zapadziko lapansi. Mu 1879, Cliff, wa ku Sweden, anapeza chinthu china chotchedwa holmium ndipo anachitcha kuti holmium kuchokera ku dzina la malo a Stockholm, likulu la dziko la Sweden.
Munda wa ntchito waholmiumikufunikabe kupititsa patsogolo, ndipo mlingo wake si waukulu kwambiri. Posachedwapa, bungwe la Baotou Steel Rare Earth Research Institute latengera ukadaulo woyeretsa wotentha kwambiri komanso wothira utupu kuti apange holmium yachitsulo yotsika kwambiri yokhala ndi zonyansa zosadziwika bwino padziko lapansi/ Σ RE>99.9％. Pakali pano, ntchito zazikulu holmium ndi awa.
(1) Monga chowonjezera cha nyali zachitsulo za halide, nyali zachitsulo za halide ndi mtundu wa nyali zotulutsa mpweya zomwe zimapangidwa pamaziko a nyali zamphamvu kwambiri za mercury, zomwe zimadziwika ndi kudzaza babu ndi mitundu yosiyanasiyana yapadziko lapansi. Pakadali pano, ntchito yayikulu ndi ayodini wapadziko lapansi osowa, omwe amatulutsa mitundu yowoneka bwino pakutulutsa mpweya. Chogwiritsidwa ntchito mu nyali za holmium ndi holmium iodide, yomwe imatha kukwaniritsa kuchuluka kwa maatomu achitsulo mu arc zone, kuwongolera kwambiri mphamvu ya radiation.
(2)Holmiumitha kugwiritsidwa ntchito ngati chowonjezera chachitsulo cha yttrium kapena yttrium aluminium garnet.
(3) Ho: YAG doped yttrium aluminium garnet imatha kutulutsa 2 μ M laser, kuchuluka kwa mayamwidwe a minofu yamunthu ku 2um laser ndikokwera, pafupifupi maulalo atatu apamwamba kuposa a Hd: YAG. Chifukwa chake mukamagwiritsa ntchito Ho: YAG laser pakuchita opaleshoni yachipatala, sikuti kuchita bwino kwa opaleshoniyo komanso kulondola kungawongoleredwe, komanso malo owonongeka amafuta amatha kuchepetsedwa kukhala ochepa. Mtengo waulere wopangidwa ndi makhiristo a holmium amatha kuchotsa mafuta osatulutsa kutentha kwambiri, potero amachepetsa kuwonongeka kwamafuta athanzi. Akuti chithandizo cha laser cha holmium cha glaucoma ku United States chingachepetse ululu wa odwala ochitidwa opaleshoni. China 2 μ Mulingo wa ma kristalo a laser wafika pamlingo wapadziko lonse lapansi, ndipo kuyesetsa kukulitsa ndi kupanga mtundu uwu wa kristalo wa laser.
(4) Mu magnetostrictive aloyi Terfenol D, pang'ono holmium akhoza kuonjezedwa kuchepetsa munda kunja chofunika machulukitsidwe maginito a aloyi.
(5) Kuphatikiza apo, ulusi wa holmium doped ukhoza kugwiritsidwa ntchito kupanga zida zoyankhulirana zowoneka bwino monga ma fiber lasers, ma fiber amplifiers, ndi masensa a ulusi, zomwe zingathandize kwambiri pakukula mwachangu kwa kulumikizana kwa fiber masiku ano.
