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

(Er,Yb: phosphate glass) hoʻohui i ke ola lōʻihi (~ 8 ms) o ka pae laser ma 4 I 13/2 Er 3+ me ka haʻahaʻa (2-3 ms) o ka pae 4 I 11/2 Er 3+ Lifetime, hiki ke hoʻoulu i ka resonance F 5/2 hauʻoli mokuʻāina me Yb 3+ 2 . ʻO ka hoʻomaha hoʻomaha multiphonon nonradiative wikiwiki mai ka 4 I 11/2 a i ka 4 I 13/2 ma muli o ka pilina ma waena o Yb 3+ a me Er 3+ iona i hoʻohauʻoli ʻia ma 2 F 5/2 a me 4 I 11/2, kēlā me kēia, ʻo kēia pae ikehu e hoʻemi nui i ka hoʻololi ʻana o ka ikehu hope a me ka lilo o ka hoʻololi ʻana.
Er 3+ , Yb 3+ co-doped yttrium alumina aluminate borate (Er, Yb:YAB) crystals ua hoʻohana mau ʻia ʻo Er, Yb: phosphate glass alternatives a hiki ke hoʻohana ʻia ma ke ʻano he "eye-safe" active media (1,5 -1,6 μm) lasers me ka mana kiʻekiʻe o ka mana puka ma CW a me nā mode pulsed. Hōʻike ʻia ʻo ia e ka conductivity thermal kiʻekiʻe o 7,7 Wm-1 K-1 a me 6 Wm-1 K-1 ma ke ʻano a-axis a me c-axis, kēlā me kēia. He kiʻekiʻe ka hana Yb 3+→Er 3+ ka hoʻoili ikehu (~ 94%) a me ka nawaliwali o ka upconversion nalowale i pili i ke ola pōkole loa (~ 80 ns) o ka 4 I 11/2 hauʻoli mokuʻāina ma muli o ka mea hoʻokipa. Ua ʻike ʻia kahi pūnaʻi absorption ikaika a ākea (e pili ana i 17 nm) ma 976 nm, kūlike me ka spectrum emission o kahi diode laser InGaAs.
