Er, YB:YAB-Er, Yb Co – Doped Phosphate Glass
Product Description
(Er, Yb: phosphate iav) ua ke lub neej ntev (~ 8 ms) ntawm qib laser ntawm 4 I 13/2 Er 3+ nrog qis (2-3 ms) ntawm 4 I 11/2 Er 3+ qib Lub neej, tuaj yeem tsim resonance F 5/2 zoo siab lub xeev nrog Yb 3+ 2 . Fast nonradiative multiphonon so los ntawm 4 I 11/2 mus rau 4 I 13/2 vim muaj kev cuam tshuam ntawm Yb 3+ thiab Er 3+ ions txaus siab ntawm 2 F 5/2 thiab 4 I 11/2, raws li, lub zog theem no zoo heev txo cov rov qab zog hloov mus thiab nce-hloov pauv poob.
Er 3+, Yb 3+ co-doped yttrium aluminium aluminate borate (Er, Yb: YAB) crystals feem ntau siv Er, Yb: phosphate iav lwm txoj kev thiab siv tau raws li "qhov muag-kev nyab xeeb" active media (1,5 -1 , 6 μm) lasers nrog siab nruab nrab tso zis hwj chim nyob rau hauv CW thiab mem tes hom. Nws yog tus cwj pwm los ntawm cov thermal conductivity ntawm 7,7 Wm-1 K-1 thiab 6 Wm-1 K-1 raws lub a-axis thiab c-axis, feem. Kuj tseem muaj kev ua haujlwm siab Yb 3+ → Er 3+ lub zog hloov pauv (~ 94%) thiab tsis muaj zog hloov pauv tau los ntawm lub neej luv luv (~ 80 ns) ntawm 4 I 11/2 zoo siab lub xeev vim yog tus tswv tsev Lub siab tshaj plaws phonon zog siab (vmax ~ 1500 cm-1). Lub zog nqus thiab dav dav (txog 17 nm) tau pom ntawm 976 nm, zoo ib yam nrog cov emission spectrum ntawm InGaAs laser diode.
