Abstract

This paper reports that upconversion phenomenon exists in Tm³⁺-doped tellurite glass by pumping with both 793nm and 1064nm lasers. Strong 785nm two-photon upconversion fluorescence of ¹G₄ → ³H₅ transition and weak three-photon upconversion 710nm, 677nm, fluorescence pumped by 793 nm Ti:Al₂O₃ laser has been observed firstly in Tm³⁺-doped tellurite glass. Upconversion has also been observed under excitation at 1064nm.
