Kwisiqingatha sesibini senkulungwane ye-19, ukufunyanwa kohlalutyo lwe-spectroscopic kunye nokupapashwa kweetheyibhile ze-periodic tables, kunye nokuqhubela phambili kweenkqubo zokwahlula i-electrochemical element ezinqabileyo zomhlaba, kwakhuthaza ngakumbi ukufunyanwa kwezinto ezintsha ezinqabileyo zomhlaba. Ngowe-1879, uCliff, waseSweden, wafumanisa into ebizwa ngokuba yi<em>holmium waza wayibiza ngokuba yi<em>holmium ngegama lendawo yaseStockholm, ikomkhulu laseSweden.
Indawo yesicelo yeiholmiumisafuna uphuhliso olongezelelweyo, kwaye idosi ayinkulu kakhulu. Kutshanje, i-Baotou Steel Rare Earth Research Institute yamkele itekhnoloji yokucoca ubushushu obuphezulu kunye nephezulu yokucoca i-vacuum ukuze iphuhlise i-holmium yentsimbi ecocekileyo enomxholo ophantsi kakhulu wokungacoceki komhlaba okungaqhelekanga/ Σ RE>99.9％. Okwangoku, olona setyenziso luphambili holmium zezi zilandelayo.
(1) Njengesongezo sezibane ze-metal halide, izibane ze-metal halide luhlobo lwesibane sokukhupha igesi esiphuhliswe ngokwesiseko sezibane zemercury ezinoxinzelelo oluphezulu, eziphawulwa ngokuzalisa ibhalbhu ngeehalidi ezahlukeneyo zomhlaba ezinqabileyo. Okwangoku, usetyenziso oluphambili luyi-iodide yomhlaba enqabileyo, ekhupha imibala eyahlukeneyo ye-spectral ngexesha lokukhutshwa kwegesi. Into esebenzayo esetyenziswa kwizibane ze-holmium yi-holmium iodide, enokufikelela kwi-concentration ephezulu yee-athomu zetsimbi kwindawo ye-arc, iphucula kakhulu ukusebenza kakuhle kwemitha.
(2)IHolmiumingasetyenziselwa njengesongezo sentsimbi ye-yttrium okanye i-yttrium aluminium garnet.
(3) Ho: I-YAG doped yttrium aluminium garnet inokukhupha i-2 μ M laser, izinga lokufunxa kwezicubu zomntu ukuya kwi-2um laser liphezulu, phantse imiyalelo emithathu yobukhulu obuphezulu kune-Hd: YAG. Ngoko xa usebenzisa i-Ho: i-laser ye-YAG ukwenzela utyando lwezonyango, kungekhona nje ukuphuculwa kokusebenza kotyando kunye nokuchaneka, kodwa kunye nendawo yokulimala kwe-thermal ingancitshiswa ibe yincinci. Umqadi okhululekileyo owenziwe yi-holmium crystals unokuphelisa amanqatha ngaphandle kokuvelisa ubushushu obugqithisileyo, ngaloo ndlela unciphisa umonakalo oshushu kwizicubu eziphilileyo. Kunikelwa ingxelo yokuba unyango lwe<em>holmium laser lweglaucoma eUnited States lunokuzinciphisa iintlungu zabaguli abatyandwayo. I-China 2 μ Inqanaba le-m laser crystals lifikelele kwinqanaba lamazwe ngamazwe, kwaye kufuneka kwenziwe iinzame zokuphuhlisa nokuvelisa olu hlobo lwe-laser crystal.

(5) Ukongezelela, i-holmium doped fibers ingasetyenziselwa ukwenza izixhobo zokunxibelelana nge-optical ezifana ne-fiber lasers, i-fiber amplifiers, kunye ne-fiber sensors, eya kudlala indima ebalulekileyo ekuphuhliseni ngokukhawuleza konxibelelwano lwefayibha namhlanje.
