Er, YB: YAB-Er, Yb Co - Ikirahure cya Fosifate

. Ubuzima bwose, bushobora kubyara resonance F 5/2 leta yishimye hamwe na Yb 3+ 2. Kwihuta kwinshi kwa multhonon kuva 4 I 11/2 kugeza 4 I 13/2 kubera imikoranire hagati ya Yb 3+ na Er 3+ ion yishimiye 2 F 5/2 na 4 I 11/2, urwego rwingufu rugabanya cyane gusubiza inyuma ingufu no gutakaza igihombo.
Er 3+, Yb 3+ bafatanije na yttrium aluminium aluminate borate (Er, Yb: YAB) kristu ikoreshwa cyane Er, Yb: ibirahuri bya fosifate kandi birashobora gukoreshwa nkibitangazamakuru bikora "bitagira ijisho" (1.5 -1 , 6 μm) laseri hamwe nimbaraga zo hejuru zisohoka imbaraga muri CW hamwe na pulsed modes. Irangwa nubushyuhe bwo hejuru bwa 7,7 Wm-1 K-1 na 6 Wm-1 K-1 ukurikije a-axis na c-axis. Ifite kandi imikorere myiza Yb 3 + → Er 3+ ihererekanyabubasha (~ 94%) hamwe no gutakaza intege nke za upconversion biterwa nubuzima buke cyane (~ 80 ns) bwa 4 I 11/2 leta yishimye bitewe nuwakiriye ingufu za fononi ntarengwa ni muremure (vmax ~ 1500 cm-1). Itsinda rikomeye kandi ryagutse (hafi 17 nm) ryagaragaye kuri 976 nm, rijyanye no gusohora imyuka ya diGode ya InGaAs.
