Ngowe-1843, uMossander waseSweden wafumanisa i-element erbium. Iimpawu ezibonakalayo ze-erbium zivelele kakhulu, kunye nokukhutshwa kokukhanya kwi-1550mm ye-EP +, ehlala ixhalabile, inokubaluleka okukhethekileyo kuba le mitha ye-wavelength ibekwe ngokuchanekileyo kwi-perturbation ephantsi ye-fiber optical kunxibelelwano lwefiber.ErbiumI-ion (Er *) ivuyiswa kukukhanya kwi-wavelengths ye-880nm kunye ne-1480mm, kunye nokuguquka ukusuka kwi-state efakwe kwi-415/2 ukuya kwi-213/2 yorhwebo. Xa i-Er * ikwimeko yoguqulo lwamandla aphezulu ibuyela kumhlaba ophantsi, ikhupha ukukhanya kwe-wavelength eyi-1550mm, iifiber ze-Quartz optical zinokusasaza amaza ohlukeneyo okukhanya, kodwa izinga lokuthomalalisa ukukhanya liyahluka. I-fiber optical ene-1550mm inethiwekhi ye-frequency inexesha eliphantsi lokuhanjiswa kwe-optical kwi-quartz optical fibers (o. 15a1 / krm), phantse ifikelele kumda ophantsi womfanekiso.
(1) Ngoko ke, xa unxibelelwano lwe-fiber optic lusetyenziswa njengokukhanya kwesignali kwi-1550mm, ilahleko ye-optical iyancipha. Ngaloo ndlela, ukuba umzila ofanelekileyo ngaphandle kwe-doping usetyenziselwa iinkqubo zonxibelelwano, i-amplifier inokwenza ngokomgaqo we-laser. Ke ngoko, kuthungelwano lonxibelelwano olufuna ukukhulisa ubude be-1550mm/uphawu lwe-optical, i-bait doped fiber amplifiers zizinto ezibalulekileyo ezibonakalayo. Okwangoku, i-doped silica fiber amplifiers ziye zathengiswa. Ngokweengxelo, ukuze ugweme ukufunxa okungenamsebenzi, uluhlu lwe-doping ye-erbium kwifiber ngamashumi ukuya kumakhulu e-PPm (LpPm-10-.). Uphuhliso olukhawulezayo lonxibelelwano lwefiber optic luya kuvula iindawo ezintsha zokusetyenziswa kwe-erbium.
(2) Ukongeza, ikristale ye-laser ene-baited kunye nokuphuma kwayo, i-laser ye-1730nm kunye ne-1550nm laser zikhuselekile emehlweni abantu kunye nengqondo, zinomsebenzi olungileyo wokuhambisa umoya, zinamandla anamandla okungena kumsi kwindawo yedabi, ziyimfihlo entle, ziyimfihlo. akukho lula ukubonwa lutshaba, kwaye ube umahluko omkhulu xa ukhanyisa iithagethi zomkhosi. Ziye zenziwa kwi-laser rangefinder ephathekayo yokusetyenziswa emkhosini, ekhuselekileyo emehlweni abantu.
(3) I-BP+ inokongezwa kwiglasi ukwenza imathiriyeli yeglasi yomhlaba enqabileyo yelaser, okwangoku eyimathiriyeli yelaser eqinile eneyona mveliso iphezulu yepulse amandla kunye namandla aphumayo.
(4) I-Ep + ingasetyenziselwa njenge-ion yokuvuselela ukuguqula izinto ze-laser.
(5) Ukongeza, i-erbium inokusetyenziselwa ukuguqula umbala kunye nokufakwa kombala kwiilensi zeglasi kunye neglasi yekristale.
