Er:Glass - Ejiri 1535 Nm Laser Diodes gbapụtara
Nkọwa ngwaahịa
Ọ dịkwa mma maka ngwa ahụike ebe mkpa nchekwa anya nwere ike isi ike ijikwa ma ọ bụ ibelata ma ọ bụ gbochie nleba anya dị mkpa.N'oge na-adịbeghị anya, a na-eji ya na nkwurịta okwu fiber optic kama EDFA maka nnukwu gbakwunyere ya.Enwere nnukwu ọganihu na ngalaba a.
EAT14 bụ Erbium Glass doped na Er 3+ na Yb 3+ ma dabara na ngwa metụtara ọnụego nkwughachi dị elu (1 - 6 Hz) ma jiri 1535 nm laser diodes gbapụta.Iko a dị na ọkwa dị elu nke Erbium (ruo 1.7%).
Cr14 bụ Erbium Glass doped na Er 3+, Yb 3+ na Cr 3+ ma dabara na ngwa metụtara xenon lamping.A na-ejikarị iko a eme ihe na ngwa laser range finder (LRF).
Anyị na-enwekwa agba dị iche iche nke Er: iko, dị ka odo odo, akwụkwọ ndụ akwụkwọ ndụ, na na .Ị nwere ike hazie niile udi nke ya. Nye m kpọmkwem parameters ma ọ bụ eserese ka mma anyị engineer ikpe ikpe.
