Er,YB:YAB-Er, Yb Co – Doped Phosphate Glass
Whakaahuatanga Hua
(Er,Yb: phosphate glass) ka whakakotahi i te roa o te oranga (~8 ms) o te taumata laser i runga i te 4 I 13/2 Er 3+ me te iti (2-3 ms) o te taumata 4 I 11/2 Er 3+ Te ora, ka taea te whakaputa i te resonance F 5/2 te ahua hikaka me te Yb 3+ 2 . He tere te whakangā o te maha o nga katote-kore i te 4 I 11/2 ki te 4 I 13/2 na te tauwhitinga i waenga i nga katote Yb 3+ me te Er 3+ e hikaka ana i te 2 F 5/2 me te 4 I 11/2, ka tino whakaitihia e tenei taumata kaha te whakawhiti pūngao hoki me te mate-whakawhitinga ake.
Er 3+ , Yb 3+ yttrium konumohe aluminate borate (Er,Yb:YAB) ka whakamahia nga tioata Er, Yb: phosphate glass alternatives and can be used as “kanohi-haumaru” active media ( 1,5 -1 ,6 μm) lasers me te teitei o te mana whakaputa toharite i roto i te CW me nga momo pupuhi. Ko te ahua o te kawe werawera teitei o te 7,7 Wm-1 K-1 me te 6 Wm-1 K-1 i te taha o te tuaka-a me te tuaka-c. He kaha hoki te kaha o te Yb 3+→Er 3+ te whakawhiti pūngao (~94%) me te ngoikoretanga o te whakahuritanga i te wa poto (~ 80 ns) o te 4 I 11/2 te ahua hikaka na te kaha o te kaihautu. he teitei (vmax ~1500 cm-1). I kitea he roopu whakauru kaha me te whanui (e tata ana ki te 17 nm) i te 976 nm, e rite ana ki te awhi tukunga o te ngohe laser InGaAs.
