Abstract

Visible and ultraviolet upconversion (UC) emission is observed under 800 nm femtosecond laser excitation in LiNbO₃ crystals triply doped with Tm³⁺, Yb³⁺, and Nd³⁺ at room temperature. Energy transfer (ET) from Nd³⁺ to Yb³⁺ then to Tm ³⁺ is very important in this UC emission process. The overlapping between the emissions of ¹D₂ → ³F ₄ and ¹G₄ → ³H₆, which makes up of blue emission band, is confirmed by transient investigation. From the pump energy dependence investigation, it is known that the dominant populating mechanism for the ¹G₄ state is the two-photon process, and that for ¹D₂ is the three-photon process. In our UC emission model, the ¹G₄ state is populated by the ET of ²F_5/2(Yb³⁺)+³H ₄(Tm³⁺) → ²F_7/2(Yb ³⁺) +¹G₄(Tm³⁺), ¹D ² state is populated by the ET of ³F₂+ ³H₄ → ¹D₂+ ³H ₆ among Tm³⁺ ions. For LiNbO₃ crystals doped with Tm³⁺ to the concentration of 0.9 mol %, the measured lifetimes of ¹G₄ and ¹D₂ are ∼ 80 and 4 μs.
