Xyoo 1843, Mossander ntawm Sweden tau tshawb pom lub ntsiab erbium. Cov khoom kho qhov muag ntawm erbium yog qhov tseem ceeb heev, thiab lub teeb emission ntawm 1550mm ntawm EP +, uas ib txwm muaj kev txhawj xeeb, muaj qhov tseem ceeb tshwj xeeb vim tias qhov wavelength no yog qhov tseeb nyob rau hauv qhov qis tshaj perturbation ntawm optical fiber hauv kev sib txuas lus fiber ntau.Erbiumions (Er *) zoo siab los ntawm lub teeb ntawm wavelengths ntawm 880nm thiab 1480mm, thiab kev hloov ntawm lub xeev teeb tsa 415/2 mus rau lub xeev kev lag luam 213/2. Thaum Er * nyob rau hauv lub xeev high-zog hloov mus rau hauv av xeev, nws emits 1550mm wavelength teeb, Quartz optical fibers yuav kis tau ntau yam wavelengths ntawm lub teeb, tab sis lub teeb attenuation tus nqi sib txawv. Optical fiber ntau nrog 1550mm zaus network muaj qhov qis tshaj plaws ntawm lub sijhawm sib kis hauv quartz optical fibers (o. 15a1 / krm), yuav luag ncav cuag qhov qis ntawm daim duab.
(1) Yog li ntawd, thaum fiber ntau optic kev sib txuas lus yog siv raws li lub teeb liab teeb liab ntawm 1550mm, lub optical poob yog tsawg. Nyob rau hauv no txoj kev, yog hais tias ib tug haum txoj kab uas tsis muaj doping yog siv rau kev sib txuas lus systems, lub amplifier yuav ua tau raws li lub hauv paus ntsiab lus ntawm laser. Yog li ntawd, nyob rau hauv kev sib txuas lus tes hauj lwm uas yuav tsum tau amplify wavelength 1550mm / optical teeb liab, bait doped fiber amplifiers yog qhov tseem ceeb kho qhov muag Cheebtsam. Tam sim no, doped silica fiber amplifiers tau ua lag luam. Raws li cov lus ceeb toom, txhawm rau kom tsis txhob muaj kev nqus tsis zoo, qhov doping ntau ntawm erbium hauv fiber ntau yog kaum rau pua pua PPm (LpPm-10-.). Kev loj hlob sai ntawm kev sib txuas lus fiber ntau optic yuav qhib qhov chaw tshiab rau kev siv erbium.
(2) Tsis tas li ntawd, baited laser siv lead ua thiab nws cov zis, 1730nm laser thiab 1550nm laser muaj kev nyab xeeb rau tib neeg lub qhov muag thiab lub hlwb, muaj kev ua haujlwm zoo hauv huab cua, muaj peev xwm nkag mus rau cov pa luam yeeb hauv tshav rog, muaj kev ruaj ntseg zoo, yog tsis yooj yim kom pom los ntawm cov yeeb ncuab, thiab muaj qhov sib txawv loj thaum teeb pom kev ua tub rog lub hom phiaj. Lawv tau raug tsim los rau hauv lub portable laser rangefinder rau kev siv tub rog, uas muaj kev nyab xeeb rau tib neeg lub qhov muag.
(3) BP + tuaj yeem muab ntxiv rau iav kom tsis tshua muaj lub ntiaj teb iav laser cov ntaub ntawv, uas tam sim no yog cov khoom siv hluav taws xob hauv lub xeev laser nrog cov khoom siv hluav taws xob siab tshaj plaws thiab lub zog tso zis.
(4) Ep + tuaj yeem siv los ua kev ua kom ion rau kev hloov cov ntaub ntawv laser.
(5) Tsis tas li ntawd, erbium kuj tuaj yeem siv rau decolorization thiab xim ntawm cov iav tsom iav thiab iav crystalline.
