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

(Er,Yb: phosphate glass) e kopanya nako e telele ea bophelo (~8 ms) ea boemo ba laser ho 4 I 13/2 Er 3+ le tlaase (2-3 ms) ea 4 I 11/2 Er 3+ level Lifetime, e ka hlahisa resonance F 5/2 boemo ba thabo ka Yb 3+ 2 . Fast nonradiative multiphonon relaxation ho tloha 4 I 11/2 ho 4 I 13/2 ka lebaka la ho sebelisana pakeng tsa Yb 3+ le Er 3+ ions e thabetse 2 F 5/2 le 4 I 11/2, ka ho latellana , matla ana a matla a fokotsa haholo morao phetisetso ea matla le tahlehelo ea ho fetola matla.
Er 3+ , Yb 3+ co-doped yttrium aluminium aluminate borate (Er,Yb:YAB) likristale li sebelisoa ka tloaelo Er,Yb: phosphate glass alternatives 'me li ka sebelisoa e le "leihlo le bolokehileng" mecha ea litaba e sebetsang (1,5 -1,6 μm) e nang le matla a phahameng a tlhahiso ea matla ka CW le mekhoa ea pulsed. E tšoauoa ka conductivity e phahameng ea mocheso oa 7,7 Wm-1 K-1 le 6 Wm-1 K-1 hammoho le a-axis le c-axis, ka ho latellana. E boetse e na le ts'ebetso e phahameng ea Yb 3+→Er 3+ phetisetso ea matla (~94%) le tahlehelo e fokolang ea phetoho e hlahisoang ke nako e khuts'oane haholo ea bophelo (~80 ns) ea boemo bo thabileng ba 4 I 11/2 ka lebaka la moamoheli Matla a phahameng a phonon a phahame (vmax ~1500 cm-1). Sehlopha se matla le se pharaletseng sa ho monya (hoo e ka bang 17 nm) se ile sa bonoa ho 976 nm, se tsamaellanang le khanya ea tlhahiso ea laser diode ea InGaAs.
