Optical-absorption spectrum of Ho3+ ions in oxyfluoride glass ceramic was measured, from which the measured oscillator strengths were obtained. The Judd-Ofelt intensity param- etersΩ( = 2,4,6) were determined by a best fit of the calculated and measured oscillator strengths, the rms deviation was 3.5 ×10-7. Some predicted spectroscopic parameters of the ex- cited states, like the spontaneous radiative transition rate, radiative lifetime, branching ratio and integrated emission cross section were given using the intensity parameters. The spectroscopic parameters were comparable with some laser materials, and some of them were better.
