Muna 1843, Mossander yekuSweden yakawana element erbium.Iyo optical properties yeerbium yakakurumbira zvikuru, uye chiedza chinobuda pa1550mm yeEP+, iyo yagara ichinetsa, ine kukosha kwakakosha nokuti iyi wavelength inonyatsowanikwa panzvimbo yakaderera zvikuru ye optical fiber mu fiber communication.Erbiumions (Er *) inonakidzwa nechiedza pawavelengths ye880nm uye 1480mm, uye shanduko kubva kune yakaiswa 415/2 kuenda kune yekutengeserana nyika 213/2.Kana Er * iri munzvimbo ine simba repamusoro-soro ichichinja kudzokera kupasi, inoburitsa 1550mm wavelength mwenje, Quartz optical fibers inogona kufambisa akasiyana mafungu echiedza, asi mwero wekudzikisa chiedza unosiyana.Iyo optical fiber ine 1550mm frequency network ine yakaderera optical transmission nguva mu quartz optical fibers (o. 15a1 / krm), inenge ichisvika kumucheto wakaderera wemufananidzo.
(1) Saka, kana fiber optic kutaurirana inoshandiswa sechiedza chechiratidzo pa 1550mm, kurasikirwa kwemaziso kunoderedzwa.Nenzira iyi, kana nzira yakakodzera isina doping inoshandiswa kune masisitimu ekutaurirana, iyo amplifier inogona kuita zvinoenderana nemusimboti welaser.Naizvozvo, mumatanho enharembozha anoda kukwidziridza wavelength 1550mm/optical siginecha, chirauro doped fiber amplifiers zvinhu zvakakosha zvemaziso.Parizvino, doped silica fiber amplifiers yakatengeswa.Maererano nemishumo, kuitira kuti udzivise kunyura kusina maturo, doping range ye erbium mufiber iri makumi kusvika kumazana ePPm (LpPm-10-.).Iko kukurumidza kuvandudza kwefiber optic kutaurirana kuchavhura minda mitsva yekushandiswa kweerbium.
(2) Pamusoro pezvo, iyo baited laser crystal uye kubuda kwayo, iyo 1730nm laser uye 1550nm laser yakachengeteka kumaziso emunhu nehuropi, ine yakanaka yemhepo yekutapurirana kuita, ine simba rakasimba rekupinda muutsi munhandare yehondo, kuva nekuvanzika kwakanaka. hazvisi nyore kuti zvionekwe nemuvengi, uye uve nemusiyano wakakura paunenge uchivhenekera zvinangwa zvemauto.Ivo vakaitwa inotakurika laser rangefinder yekushandiswa kwemauto, iyo yakachengeteka kumaziso evanhu.
(3) BP + inogona kuwedzerwa kugirazi kugadzira isingawanzo pasi girazi laser zvinhu, izvo parizvino solid-state laser zvinhu zvine yakanyanya kubuda pulse simba uye kubuda simba.
(4) Ep + inogona zvakare kushandiswa se activation ion yekushandura laser zvinhu.
(5) Pamusoro pezvo, erbium inogona zvakare kushandiswa kugadzira decolorization uye kupenda kwegirazi remaziso uye girazi rekristaro.
