Abstract

The study of neodymium ions emission along the channel ⁴F_3/2->⁴I_9/2 led us to select several materials for short laser wavelength application. The results obtained with three series of compounds are presented: ABGa₃O₇ (A = Ca or Sr-B = La or Gd), ABAlO₄ (A = Ca or Sr-B = Y, Ln) and AMO₄ (A= Ca, Sr or Ba-M = Mo or W). Crystal growth of these hosts and neodymium ions spectroscopic characterizations are presented. Among all these crystals, Nd-doped BaWO₄ seems to be the most promising one for laser emission at short wavelength, combining easy crystal growth, short emission wavelength and long lifetime.
