Abstract
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 la ser performances of Nd : NYW crystals with different concentrations are com pared for the first time. The Nd3+ concentrations used are 1, 2, 4 and 5 at %. Our investigation shows that 2 at% is the optimum concentration. When th e incident pump power is 575 mw, the 1.06 mum output can reach 184 mW, corr esponding to an optical-to-optical efficiency of 32%. We believe that our w ork is significant for the further research and actual application of this promising laser crystal. (C) 2001 Elsevier Science Ltd. All rights reserved .
