Mu 1843, Mossander wo muri Suwede yavumbuye ikintu erbium.Imiterere ya optique ya erbium iragaragara cyane, kandi imyuka yoherezwa kuri 1550mm ya EP +, yamye ihangayikishije, ifite umumaro wihariye kuko ubu burebure bwumurongo ubarizwa muburyo bwo hasi cyane bwa fibre optique mugutumanaho kwa fibre.Erbiumion (Er *) bashimishwa numucyo muburebure bwa 880nm na 1480mm, no kuva muri leta yashyizweho 415/2 ukajya mubucuruzi 213/2.Iyo Er * mu mbaraga nyinshi za leta zisubira inyuma zubutaka, zisohora urumuri rwumurambararo wa 1550mm, fibre optique ya Quartz irashobora kohereza uburebure butandukanye bwumucyo, ariko igipimo cyumucyo kiratandukanye.Fibre optique hamwe numuyoboro wa 1550mm yumurongo ufite igihe gito cyo kohereza optique muri fibre optique (o. 15a1 / krm), hafi kugera kumupaka wo hasi wishusho.
(1) Kubwibyo, iyo itumanaho rya fibre optique rikoreshwa nkurumuri rwibimenyetso kuri 1550mm, igihombo cya optique kiragabanuka.Muri ubu buryo, niba inzira ikwiye idafite doping ikoreshwa muri sisitemu yitumanaho, amplifier irashobora gukora ikurikije ihame rya laser.Kubwibyo, murusobe rwitumanaho rugomba kongera uburebure bwa 1550mm / ibimenyetso bya optique, ibyuma byongera fibre byongera ibikoresho byingenzi bya optique.Kugeza ubu, ibyuma byongera imbaraga bya silika fibre byongerewe ibicuruzwa.Nk’uko raporo zibyerekana, mu rwego rwo kwirinda kwinjizwa bidafite akamaro, urugero rwa doping ya erbium muri fibre ni icumi kugeza kuri magana PPm (LpPm-10-.).Iterambere ryihuse ryitumanaho rya fibre optique rizafungura imirima mishya yo gukoresha erbium.
. ntibyoroshye kumenyekana numwanzi, kandi bifite itandukaniro rinini mugihe umurikira ibitero bya gisirikare.Byakozwe muburyo bwa lazeri ishobora gukoreshwa kugirango ikoreshwe mu gisirikare, itekanye ku maso y'abantu.
.
(4) Ep + irashobora kandi gukoreshwa nka ion yo gukora kugirango ihindure ibikoresho bya laser.
