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

(Er,Yb: ingilazi ye-phosphate) ihlanganisa impilo ende (~8 ms) yezinga le-laser ku-4 I 13/2 Er 3+ nokuphansi (2-3 ms) kwezinga le-4 I 11/2 Er 3+ Ukuphila konke, kungenza i-resonance F 5/2 isimo sokuthokoza nge-Yb 3+ 2 . Ukuphumula okusheshayo okungenayo imisebe ye-multiphonon kusuka ku-4 I 11/2 kuya ku-4 I 13/2 ngenxa yokusebenzisana phakathi kwe-Yb 3+ ne-Er 3+ ion ejatshuliswe ku-2 F 5/2 kanye no-4 I 11/2, ngokulandelana, leli zinga lamandla linciphisa kakhulu ukudluliswa kwamandla emuva kanye nokulahlekelwa kokuguqulwa okuphezulu.
Er 3+ , Yb 3+ co-doped yttrium aluminium aluminate borate (Er,Yb:YAB) amakristalu avame ukusetshenziswa Er,Yb:phosphate glass alternatives futhi angasetshenziswa njengemidiya esebenzayo “evikela amehlo” ( 1,5 -1 ,6 μm) ama-lasers anamandla okukhiphayo amaphakathi aphezulu ku-CW nezindlela ezishaya ngamandla. Ibonakala ngokusebenza okuphezulu kokushisa okungu-7,7 Wm-1 K-1 kanye no-6 Wm-1 K-1 eduze kwe-axis ne-c-eksisi, ngokulandelana. Futhi inokusebenza kahle okuphezulu kwe-Yb 3+→Er 3+ ukudluliselwa kwamandla (~94%) kanye nokulahlekelwa ukuguqulwa okubuthakathaka okubangelwa isikhathi esifushane kakhulu sempilo (~80 ns) sesimo senjabulo esingu-4 I 11/2 ngenxa ye-The maximum phonon energy iphezulu (vmax ~1500 cm-1). Ibhendi yokumunca eqinile nebanzi (cishe i-17 nm) ibonwe ku-976 nm, ehambisana ne-spectrum yokukhishwa kwe-InGaAs laser diode.
