Abstract: The spectral-luminescent properties of Er<superscript>3+</superscript>,Yb<superscript>3+</superscript>:YMgB<subscript>5</subscript>O<subscript>10</subscript> were investigated. The spectra of the cross section of absorption and stimulated emission in polarized light were determined. The lifetimes of the erbium <superscript>4</superscript>I<subscript>13/2</subscript> and ytterbium <superscript>2</superscript>F<subscript>5/2</subscript> energy levels were measured. The Yb<superscript>3+</superscript> → Er<superscript>3+</superscript> energy transfer efficiency was estimated. Within the framework of the conventional Judd–Ofelt theory the strengths of absorption and emission transitions were calculated, which made it possible to determine the lifetime of the Er<superscript>3+</superscript> excited energy levels as well as the luminescence branching ratios.
