The Jadd-Ofelt parameters for thulium ions in fluorophosphate glasses with different phosphate content are calculated. The proximity of the values of the parameters Ωt of glasses with a content of up to 10 mol% Ba(PO3)2 to the similar parameters of the fluoride glasses and a sharp increase in their values with a further increase in phosphates are shown. In the framework of the Jadd-Ofelt theory, the spectral-luminescent parameters of glasses are analyzed. The spontaneous transitions probabilities, branching coefficients (β), and radiation lifetimes (τrad) for various excited states of Tm3+ ions are obtained. It was found that, at low phosphate concentrations, glasses have a high radiation lifetime for the excited 3F4 laser level. It has been shown that the glasses with a content of up to 10 mol% Ba(PO3)2 are characterized by a wide flat gain spectrum, which makes them promising materials for creating broadband amplifiers.
