We have measured the transmission and emission spectra of a new crystal, Nd:NaY(WO4)2 (Nd:NYW). Using a Ti:sapphire laser as the pump source, the laser performances of Nd:NYW crystals with different concentrations are compared for the first time. The Nd3+ concentrations used are 1, 2, 4 and 5at % . Our investigation shows that 2at % is the optimum concentration. When the incident pump power is 575mW, the 1.06μm output can reach 184mW, corresponding to an optical-to-optical efficiency of 32 % . We believe that our work is significant for the further research and actual application of this promising laser crystal.
