Abstract
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 μm emission. The absorption and emission cross sections corresponding to the 5I 7– 5I 8 transitions of Ho 3+ (at 2.0 μm) have been calculated according to the McCumber theory. Glass sample heat-treated at 470 °C has the maximum absorption and emission cross sections of 5.58 × 10 −21 cm 2 at 1949 nm and 6.64 × 10 −21 cm 2 at 2034 nm. The Yb 3+–Ho 3+ doped oxyfluoride glass ceramic exhibits an advantage for application in 2.0 μm laser devices.
