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

(Er,Yb: iglasi yephosphate) idibanisa ubomi obude (~8 ms) kwinqanaba lelaser kwi-4 I 13/2 Er 3+ kunye nesezantsi (2-3 ms) ye-4 I 11/2 Er 3+ inqanaba loBomi, inokuvelisa i-resonance F 5/2 imo echulumancisayo nge-Yb 3+ 2. Fast nonradiative multiphonon relaxation ukusuka 4 I 11/2 ukuya 4 I 13/2 ngenxa yokusebenzisana phakathi Yb 3+ kunye Er 3+ ion imincili kwi 2 F 5/2 kunye 4 I 11/2, ngokulandelanayo , eli nqanaba lamandla linciphisa kakhulu ukuhanjiswa kwamandla ngasemva kunye nokulahlekelwa kwe-up-conversion.
Er 3+ , Yb 3+ co-doped yttrium aluminiyam ialuminiyam borate (Er,Yb:YAB) iikristale zisetyenziswa ngokuqhelekileyo Er,Yb:i-phosphate glass alternatives kwaye inokusetyenziswa “njenge-eye-eye-eye” media esebenzayo (1,5 -1,6 μm) iilaser ezine-avareji ephezulu yokuvelisa amandla kwi-CW kunye ne-pulsed modes. Ibonakaliswa ngumgangatho ophezulu we-thermal conductivity ye-7,7 Wm-1 K-1 kunye ne-6 Wm-1 K-1 kunye ne-axis kunye ne-c-axis, ngokulandelanayo. Kwakhona inokusebenza okuphezulu kwe-Yb 3+→Er 3+ ukudluliselwa kwamandla (~94%) kunye nelahleko ebuthathaka yokuguqulwa okubangelwa kubomi obufutshane kakhulu (~80 ns) be-4 I 11/2 imo echulumancisayo ngenxa ye-host's Amandla aphezulu ephonon aphezulu (vmax ~ 1500 cm-1). Ibhendi yokufunxa eyomeleleyo nebanzi (malunga ne-17 nm) yabonwa kwi-976 nm, ehambelana ne-spectrum yokukhutshwa kwe-InGaAs laser diode.
