| 英文摘要 | laser glass gain medium that can convert low cost 808 nm diode laser into 2.7 mu m has attracted considerable interest due to its potential application for medical surgery fiber laser system. in this study, enhanced 2.7 mu m emission has been achieved in er3+:germanate glass by co-doping with nd3+ ions under the excitation of an 808 nm diode laser. in the co-doped sample, the experimental results show that the harmful visible emissions via up-conversion were effectively restricted. the reduction of 1.5 mu m emission was also detected in the co-doped sample, which indicates significant de-excitation of i-4(13/2) er3+ ion through energy transfer and non-radiative decay in nd3+ ions. in conclusion, the 2.7 mu m emission enhancement achieved was due to the increased optical absorption of 808 nm, efficient energy transfer (et) with efficiency of 81.73% between er3+ and nd3+ ions, and shortening the lifetime of the lower lasing level i-4(13/2) er3+ in the co-doped sample. therefore, er3+/nd3+ co-doped germanate glass could be used to fabricate fiber optical gain media for 2.7 mu m laser generation.
