Abstract

An analysis of the spectroscopic properties of trivalent erbium doped Yb₃Al₅O₁₂ (YbAG) garnet is presented. In this work, the authors focused attention on the up-conversion processes leading to the short wavelength emission from the ²G_9/2, ⁴S_3/2 and ⁴F_9/2 excited states of Er³⁺ ions. The strong interaction between Yb³⁺ and Er³⁺ ions, responsible for the infra-red (940 nm) induced visible emissions in the 415, 550 and 670 nm range, were observed.
