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

(Er,Yb: phosphate glass) inosanganisa hupenyu hurefu (~ 8 ms) yelaser level pa4 I 13/2 Er 3+ ine yakaderera (2-3 ms) ye4 I 11/2 Er 3+ level. Hupenyu hwese, inogona kugadzira resonance F 5/2 yekunakidzwa mamiriro neYb 3+ 2. Fast nonradiative multiphonon kuzorora kubva ku4 I 11/2 kusvika 4 I 13/2 nekuda kwekudyidzana pakati peYb 3+ neEr 3+ ions inofara pa2 F 5/2 uye 4 I 11/2, zvichiteerana, iyi nhanho yesimba inoderedza zvakanyanya kumashure kwesimba rekufambisa uye kumusoro-kutendeuka kurasikirwa.
Er 3+ , Yb 3+ co-doped yttrium aluminium aluminate borate (Er,Yb:YAB) makristasi anowanzo shandiswa Er,Yb:phosphate glass alternatives uye anogona kushandiswa se“maziso-akachengeteka” anoshanda media (1,5 -1 , 6 μm) lasers ine yakakwira avhareji yekuburitsa simba muCW uye pulsed modes. Iyo inoratidzirwa nekukwirira kwekushisa kwe7,7 Wm-1 K-1 uye 6 Wm-1 K-1 pamwe nea-axis uye c-axis, zvichiteerana. Zvakare ine hunyanzvi hwepamusoro Yb 3+→Er 3+ kuchinjisa simba (~ 94%) uye isina kusimba kutendeuka kurasikirwa kunokonzerwa nehupenyu hupfupi kwazvo (~ 80 ns) ye4 I 11/2 yekunakidzwa mamiriro nekuda kwemuenzi wacho Iyo yakanyanya phonon simba. yakakwirira (vmax ~ 1500 cm-1). Bhandi rakasimba uye rakafara rekunyura (rinenge 17 nm) rakaonekwa pa976 nm, rinoenderana nekubuda kweiyo InGaAs laser diode.
