Kev Taw Qhia: Lub Ntiaj Teb Ci Ntxoov Ntxoo Los Ntawm Lasers
Hauv zej zog kev tshawb fawb, cov kev tsim kho tshiab uas tau hloov peb txoj kev xav thiab kev sib cuam tshuam nrog lub ntiaj teb no tau raug hwm. Lub laser sawv cev ua ib qho kev tsim kho tshiab loj heev, nkag mus rau ntau yam ntawm peb lub neej, los ntawm kev kho mob nyuaj mus rau lub hauv paus ntawm peb cov kev sib txuas lus digital. Qhov tseem ceeb rau kev txawj ntse ntawm cov thev naus laus zis laser yog ib qho tshwj xeeb: iav erbium-doped. Qhov kev tshawb nrhiav no nthuav tawm qhov kev tshawb fawb zoo kawg nkaus hauv qab iav erbium thiab nws cov ntawv thov dav dav uas tsim peb lub ntiaj teb niaj hnub no (Smith & Doe, 2015).
Tshooj 1: Cov Ntsiab Lus Tseem Ceeb ntawm Erbium Iav
Nkag Siab Txog Erbium Iav
Erbium, ib tug tswv cuab ntawm cov khoom siv tsis tshua muaj, nyob hauv f-block ntawm lub rooj periodic. Nws kev koom ua ke rau hauv cov iav matrices muab cov yam ntxwv zoo kawg nkaus optical, hloov cov iav ib txwm mus rau hauv ib qho chaw muaj zog uas muaj peev xwm tswj lub teeb. Pom tau los ntawm ib qho xim liab dawb, qhov sib txawv ntawm cov iav no yog qhov tseem ceeb hauv kev ua kom lub teeb ci ntsa iab, tseem ceeb rau ntau yam kev siv tshuab (Johnson & Steward, 2018).
Er, Yb: Phosphate Iav Dynamics
Qhov kev sib koom ua ke ntawm Erbium thiab Ytterbium hauv phosphate iav tsim lub hauv paus ntawm kev ua haujlwm laser, sib txawv los ntawm kev siv zog ntev 4 I 1 3/2 thiab kev hloov pauv zog zoo dua los ntawm Yb mus rau ErCov Er, Yb co-doped yttrium txhuas borate (Er, Yb: YAB) siv lead ua yog ib qho kev xaiv rau Er, Yb: phosphate iavCov khoom sib xyaw no tseem ceeb heev rau cov lasers ua haujlwm hauv "muaj kev nyab xeeb rau qhov muag"1.5-1.6μm spectrum, ua rau nws tseem ceeb heev rau ntau yam kev siv tshuab (Patel & O'Neil, 2019).

Qhov Zoo ntawm Erbium
Kev xaiv Erbium yog ua tib zoo xav, tsav los ntawm kev teeb tsa atomic uas ua rau lub teeb nqus tau zoo tshaj plaws thiab cov wavelengths tso tawm. Cov photoluminescence no yog qhov tseem ceeb rau kev tsim cov laser muaj zog thiab raug.
Cov lasers ua piv txwv txog kev sib raug zoo ntawm kev tshawb fawb thiab thev naus laus zis, uas yog ib qho pov thawj rau peb lub peev xwm los siv cov kev cai lij choj ntawm lub cev rau kev ua lag luam tshiab. Hauv qhov no, cov hlau tsis tshua muaj, tshwj xeeb tshaj yog erbium (Er) thiab ytterbium (Yb), ua lub luag haujlwm tseem ceeb vim lawv cov yam ntxwv photonic tsis sib xws.

Kev Txhais Lus Txog Laser Mechanics
Lub hauv paus tseem ceeb, lub laser yog ib lub cuab yeej uas tsav lub teeb los ntawm kev ua kom pom kev zoo, nyob ntawm seb cov electron cwj pwm hauv qee cov atoms, suav nrog erbium. Cov electrons no, thaum nqus lub zog, nce mus rau lub xeev "zoo siab", tom qab ntawd tso lub zog ua cov khoom me me lossis photons, lub hauv paus ntawm kev ua haujlwm laser.
Erbium IavLub Plawv ntawm Laser Systems
Erbium-doped fiber amplifiers(EDFAs) yog qhov tseem ceeb rau kev sib txuas lus thoob ntiaj teb, pab txhawb kev xa cov ntaub ntawv hla qhov deb heev nrog kev puas tsuaj me ntsis. Cov amplifiers no siv cov iav erbium-doped cov yam ntxwv tshwj xeeb los txhawb cov teeb liab hauv cov kav dej fiber optic, qhov kev tshawb pom tau piav qhia ntau yam los ntawm Patel & O'Neil (2019).

Tshooj 3: Cov Kev Siv Ua Haujlwm ntawm Erbium Iav
Erbium iavkev siv tau zoo yog qhov tob heev, nkag mus rau ntau lub sectors suav nrog, tab sis tsis txwv rau, kev sib txuas lus, kev tsim khoom, thiab kev kho mob.
Kev Hloov Pauv Tshiab ntawm Kev Sib Txuas Lus
Hauv cov txheej txheem sib txuas lus thoob ntiaj teb uas nyuaj heev, erbium iav yog qhov tseem ceeb heev. Nws lub peev xwm ua kom lub zog loj dua txo qhov poob ntawm cov teeb liab, ua kom muaj kev xa cov ntaub ntawv sai thiab dav, yog li ua kom cov kev sib cais thoob ntiaj teb tsawg dua thiab txhawb kev sib txuas lus tiag tiag.
Kev Txhim Kho Kev Kho Mob thiab Kev Lag Luam Ua Ntej
Erbium iavhla dhau kev sib txuas lus, nrhiav kev sib haum xeeb hauv kev kho mob thiab kev lag luam. Hauv kev kho mob, nws qhov kev ua haujlwm raug coj los siv cov laser phais, muab cov kev xaiv zoo dua, tsis cuam tshuam rau cov txheej txheem ib txwm muaj, ib qho kev kawm uas Liu, Zhang, & Wei (2020) tau tshawb nrhiav. Hauv kev lag luam, nws yog lub cuab yeej tseem ceeb hauv cov txheej txheem tsim khoom siab heev, txhawb kev tsim kho tshiab hauv cov teb xws li aerospace thiab electronics.
Xaus Lus: Lub Neej Yav Tom Ntej Uas Muaj Kev Pom Zoo Los NtawmErbium Iav
Kev hloov pauv ntawm Erbium iav los ntawm ib qho khoom tsis paub qab hau mus rau ib qho tseem ceeb ntawm thev naus laus zis niaj hnub no qhia txog tib neeg lub tswv yim. Thaum peb hla dhau qhov kev txwv tshiab ntawm kev tshawb fawb thiab thev naus laus zis, cov iav erbium-doped zoo li tsis muaj qhov kawg, qhia txog yav tom ntej uas qhov xav tsis thoob niaj hnub no tsuas yog kauj ruam mus rau qhov kev tawg tshiab ntawm tag kis (Gonzalez & Martin, 2021).
