Transparent oxyfluoride glass and glass ceramics doped with 3.0 mol% Yb 3+ and 0.5 mol% Ho 3+ ions have been prepared. The investigated samples show efficient 2.0 lm emission. The absorption and emission cross sections corresponding to the 5 I 7 -5 I 8 transitions of Ho 3+ (at 2.0 lm) have been calc
