Er,YB:YAB-Er, Yb Co – Doped Phosphate Glass

(Er,Yb: galasi la phosphate) limaphatikiza moyo wautali (~8 ms) wa mulingo wa laser pa 4 I 13/2 Er 3+ ndi otsika (2-3 ms) a 4 I 11/2 Er 3+ mlingo Moyo wonse, ukhoza kupanga resonance F 5/2 dziko losangalala ndi Yb 3+ 2 .Kupumula mwachangu kwa multiphonon kuchokera ku 4 I 11/2 mpaka 4 I 13/2 chifukwa cha kuyanjana pakati pa Yb 3+ ndi Er 3+ ma ion okondwa pa 2 F 5/2 ndi 4 I 11/2, motsatana, mphamvu iyi imachepetsa kwambiri kubwerera mphamvu kutengerapo ndi mmwamba-kutembenuka zotayika.
Er 3+ , Yb 3+ co-doped yttrium aluminium aluminiyamu borate (Er,Yb:YAB) makhiristo amagwiritsidwa ntchito kwambiri Er,Yb:galasi ya phosphate m'malo ena ndipo atha kugwiritsidwa ntchito ngati "choteteza maso" (1,5 -1) , 6 μm) ma laser okhala ndi mphamvu zambiri zotulutsa mu CW ndi mitundu yopumira.Imadziwika ndi matenthedwe apamwamba a 7,7 Wm-1 K-1 ndi 6 Wm-1 K-1 motsatana ndi axis ndi c-axis, motsatana.Komanso ili ndi mphamvu zambiri za Yb 3+→Er 3+ kutumiza mphamvu (~ 94%) ndi kutayika kofooka kosinthika komwe kumachitika chifukwa cha moyo waufupi kwambiri (~ 80 ns) wa 4 I 11/2 dziko losangalala chifukwa cha wolandirayo The maximum phonon energy ndi mkulu (vmax ~ 1500 cm-1).Bandi yamphamvu komanso yotakata (pafupifupi 17 nm) idawonedwa pa 976 nm, yogwirizana ndi kutulutsa kwa inGaAs laser diode.
