Abstract

Recently a new neodymium-doped crystal, Nd3+:KGd(WO4)2 (or Nd:KGW), lasing at 1067 nm, was demonstrated to exhibit highly efficient operation.1 The host crystal structure allows high doping (3-8 atomic percentage) without concentration quenching. Thus, higher specific energies can be achieved as compared to Nd:YAG. The crystal possesses other attractive features like broader luminescence bandwidth (24 cm-1) (which is promising for subpicosecond pulse generation) and large Raman-scattering cross section allowing for simultaneous generation of Stokes-shifted lines.
