Abstract

We report a blue emission upconversion solid-state laser based on Tm³⁺:YLF. Under double resonance excitation at 780.8 nm (near-ir) and 648.8 nm (red), the Tm³⁺ ion is sequentially excited from the ³H₆ ground state to the ¹D₂ excited state through the ³H₄ intermediate level. The laser output at 450 and 453 nm corresponds to the ¹D₂ -> ³F₄ transitions of Tm³⁺ ions in YLF.
