Abstract: We have obtained the spectral dependences of the absorption cross sections for the Ho³⁺ ⁵I₈ → ⁵I₆ and ⁵I₈ → ⁵I₇ transitions in Ho³⁺-doped aluminosilicate fibres and the spectral dependence of the stimulated emission cross section for the Ho³⁺ ⁵I₇ → ⁵I₈ laser transition in Ho³⁺-doped aluminosilicate fibre preforms. The lifetime of the Ho³⁺ ⁵I₇ upper laser level in the preforms has been determined.

Keywords: Ho³⁺ ions, aluminosilicate glass, optical fibres, luminescence, stimulated emission cross section.
