Effect of Nd3+ concentration on the laser performance of a new laser crystal:Nd:NaY (WO4)2

Journal Article


Abstract


  • 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%. Experimental results show this the work is significant to further research and practice application from this promising laser crystal.
