Ngo-1843, i-Mossander yaseSweden yathola i-element erbium. Izakhiwo ezibonakalayo ze-erbium zigqame kakhulu, futhi ukuphuma kokukhanya ku-1550mm ye-EP+, obekulokhu kukhathaza njalo, kunokubaluleka okukhethekile ngoba lobu bude begagasi butholakala ngokunembile ekuphazamisekeni okuphansi kwe-fiber optical ekuxhumaneni kwe-fiber.I-ErbiumAma-ion (Er *) ajatshuliswa ukukhanya kumaza wamaza angu-880nm no-1480mm, kanye noshintsho olusuka kusimo esifakiwe esingu-415/2 ukuya kusimo sezentengiso esingu-213/2. Lapho i-Er * esesimweni esinamandla amakhulu ishintsha ibuyela esimweni esiphansi, ikhipha ukukhanya kwe-wavelength engu-1550mm, amafiber okukhanya e-Quartz angadlulisela amaza okukhanya ahlukahlukene, kodwa izinga lokunciphisa ukukhanya liyahlukahluka. I-fiber optical enenethiwekhi yefrikhwensi engu-1550mm inesikhathi esiphansi kakhulu sokudlulisa optical kuma-quartz optical fibers (o. 15a1/krm), cishe ifinyelela umkhawulo ophansi wesithombe.
(1) Ngakho-ke, lapho ukuxhumana kwe-fiber optic kusetshenziswa njengokukhanya kwesignali ku-1550mm, ukulahlekelwa kwe-optical kuyancishiswa. Ngale ndlela, uma umzila ofanele ngaphandle kwe-doping usetshenziselwa izinhlelo zokuxhumana, i-amplifier ingenza ngokuvumelana nesimiso se-laser. Ngakho-ke, kumanethiwekhi ezokuxhumana adinga ukukhulisa ubude begagasi obungu-1550mm/i-optical signal, ama-bait doped fiber amplifiers ayingxenye ebalulekile yokubona. Njengamanje, ama-amplifiers ane-doped silica fiber asenziwe ukuhweba. Ngokwemibiko, ukuze kugwenywe ukumuncwa okungenamsebenzi, uhla lwe-doping lwe-erbium ku-fiber lungamashumi kuya kumakhulu e-PPm (LpPm-10-.). Ukuthuthukiswa okusheshayo kokuxhumana kwe-fiber optic kuzovula izinkambu ezintsha zokusetshenziswa kwe-erbium.
(2) Ngaphezu kwalokho, i-laser crystal edotshiwe kanye nokuphuma kwayo, i-laser engu-1730nm kanye ne-1550nm laser iphephile emehlweni abantu nobuchopho, inekhono elihle lokudlulisela emoyeni, inekhono eliqinile lokungena emsini enkundleni yempi, iyimfihlo enhle, iyimfihlo. akulula ukutholwa yisitha, futhi ube nomehluko omkhulu lapho ukhanyisa okuhlosiwe kwezempi. Zenziwe zaba i-laser rangefinder ephathekayo ukuze isetshenziswe empini, ephephile emehlweni abantu.
(3) I-BP+ingangezwa engilazini ukuze kwenziwe izinto ezingavamile ze-laser yengilazi yomhlaba, okwamanje okuyizinto ezisetshenziswayo ze-laser yesimo esiqinile ezinamandla aphezulu okukhipha i-pulse namandla okukhiphayo.
(4) I-Ep+ ingasetshenziswa futhi njenge-ion yokuvula yokuguqula izinto ze-laser.
(5) Ngaphezu kwalokho, i-erbium ingaphinda isetshenziselwe ukukhipha umbala kanye nemibala yamalensi engilazi yamehlo kanye nengilazi ecwebezelayo.
