摘 要：N31-type phosphate laser glasses doped with different concentrations of Cu were prepared. Their optical loss coefficient at 1053 nm wavelength and nonradiative transition rate from the Nd3+ 4F3/2 state were determined and analyzed in detail. The optical loss coefficient per unit of Cu2+ （cm-1/ppmw） and the fluorescence decay rate （Hz/ppmw） caused by Cu2+ and Nd3+ interaction were 0.0024 and 7.9, respectively. Cu impurity affected both optical loss at 1053 nm and fluorescent emission of Nd3+ 4F3/2 state seriously in N31 laser glass.
