The transmission and emission spectra of a new crystal, Nd∶NaY(WO4)2 (Nd∶NYW) have been measured. 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 5 at.-%. The experiments show that 2 at.-% is the optimum concentration. When the incident pump power is 575 mW, the 1.06 μm output can reach 184 mW, corresponding to an optical to optical efficiency of 32%. The experimental results show that the work is significant to the further research and praction application of this promising laser crystal.
