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

(Er, Yb: phosphate iko) na-ejikọta ogologo ndụ (~ 8 ms) nke ọkwa laser na 4 I 13/2 Er 3+ na ala (2-3 ms) nke 4 I 11/2 Er 3+ level Lifetime, nwere ike ịmepụta resonance F 5/2 obi ụtọ ala na Yb 3+ 2 . Ntụrụndụ multiphonon na-adịghị ngwa ngwa site na 4 I 11/2 ruo 4 I 13/2 n'ihi mmekọrịta dị n'etiti Yb 3+ na Er 3+ ion nwere obi ụtọ na 2 F 5/2 na 4 I 11/2, n'otu n'otu, ọkwa ike a na-ebelata azụ azụ ike na-efunahụ elu.
Er 3+ , Yb 3+ co-doped yttrium aluminium aluminate borate (Er, Yb: YAB) kristal na-ejikarị Er, Yb: phosphate glass alternatives na ike ji mee ihe dị ka "anya-safe" arụ ọrụ mgbasa ozi ( 1,5 -1,6 μm) lasers na elu nkezi mmepụta ike na CW na pulsed ụdịdị. A na-eji ya dị elu nke okpomọkụ nke 7,7 Wm-1 K-1 na 6 Wm-1 K-1 tinyere a-axis na c-axis, n'otu n'otu. Ọzọkwa nwere elu arụmọrụ Yb 3+→Er 3+ ike nyefe (~ 94%) na adịghị ike upconversion ọnwụ na-ekwu na obere oge ndụ (~ 80 ns) nke 4 I 11/2 obi ụtọ ala n'ihi na onye ọbịa The kacha phonon ike dị elu (vmax ~ 1500 cm-1). A hụrụ eriri mmịpụta siri ike na nke sara mbara (ihe dị ka 17 nm) na 976 nm, kwekọrọ n'ụdị ikuku ikuku nke diode laser InGaAs.
