Holmium/Ytterbium co-doped fluorophosphate glasses with compositions (80-x-y) NaPO3-10SrF2-10ZnF2- xHoF3- yYbF3 (x = 1 and y = 0.5, 1, 1.5 and 2 mol%) were prepared by melt-quenching technique. The stability criteria indicate that these glasses exhibit a good resistance against devitrification. Densities of glasses were determined and showed an almost linear variation with increase of YbF3 content. Spectroscopic parameters of Ho3+ such as radiative transition probability, branching ratio, spectroscopic quality factor, integrated emission cross section and radiative lifetime, were calculated on the basis of Judd-Ofelt analysis. The results showed that these glasses could be proposed as suitable lasing materials. © 2017 The Authors
