摘要：

Transparent oxyfluoride glass and glass ceramics doped with 3.0 mol% Yb3+ and 0.5 mol% Ho3+ ions have been prepared. The investigated samples show efficient 2.0 mu m emission. The absorption and emission cross sections corresponding to the I-5(7)-I-5(8) transitions of Ho3+ (at 2.0 mu m) have been calculated according to the McCumber theory. Glass sample heat-treated at 470 degrees C has the maximum absorption and emission cross sections of 5.58 x 10(-21) cm(2) at 1949 nm and 6.64 x 10(-21) cm(2) at 2034 nm. The Yb3+-Ho3+ doped oxyfluoride glass ceramic exhibits an advantage for application in 2.0 mu m laser devices. (c) 2010 Elsevier B.V. All rights reserved.
