Hakanan ya dace da aikace-aikacen likitanci inda buƙatar kariyar ido na iya zama da wahala a sarrafa ko ragewa ko hana mahimman abubuwan gani na gani. Kwanan nan ana amfani da shi a cikin sadarwar fiber na gani maimakon EDFA don ƙarin ƙari. Akwai babban ci gaba a wannan fanni.
EAT14 shine Gilashin Erbium da aka yi da Er 3+ da Yb 3+ kuma ya dace da aikace-aikacen da suka haɗa da ƙimar maimaitawa mai yawa (1 - 6 Hz) kuma ana yin famfo tare da diodes na laser 1535 nm. Wannan gilashin yana samuwa tare da manyan matakan Erbium (har zuwa 1.7%).
Cr14 shine Gilashin Erbium da aka yi da Er 3+, Yb 3+ da Cr 3+ kuma ya dace da aikace-aikacen da suka haɗa da famfo fitilar xenon. Ana amfani da wannan gilashin sau da yawa a aikace-aikacen gano kewayon Laser (LRF).
Har ila yau, muna da launi daban-daban na Er: gilashi, irin su purple, kore, da sauransu . Kuna iya tsara kowane nau'i na shi. Ba ni takamaiman sigogi ko zane-zane ya fi dacewa don injiniyanmu ya yi hukunci.
