Near-infrared luminescence properties of Nd and Ho ions in barium gallo-germanate glasses have been reported. Several spectroscopic parameters for Nd and Ho ions have been determined from the Judd-Ofelt analysis and absorption/luminescence measurements. Quite large luminescence lifetime, quantum efficiency and stimulated emission cross-section have been obtained for the main F → I (Nd) and I → I (Ho) laser transitions of rare earths in barium gallo-germanate glasses. It suggests that barium gallo-germanate glass is promising for near-infrared laser application at emission wavelengths 1064 nm (Nd) and 2020 nm (Ho).
