Abstract

Codoping with Zr⁴⁺ ions enhances the 1.54 μm emission in Yb/Er:LiNbO₃ crystal by about three times. Optical damage resistant Zr⁴⁺ ion increases the maximum phonon energy of Er:LiNbO₃ host, which is favorable for the nonradiative relaxation from ⁴I _11/2 to ⁴I_13/2 state (Er). The time decay spectra show that the incorporation of Zr⁴⁺ ions leads to a shortening lifetime of ⁴I_11/2 state (Er), increasing the nonradiative relaxation rate of ⁴I_11/2 → ⁴I_13/2 (Er) in Yb/Er:LiNbO₃. The 1.54 μm emission enhancement is important to telecommunication application.
