ABSTRACT:
Doped crystalline compositions (e.g., single domain crystals) of MTiOAsO.sub.4 (wherein M is K, Rb and/or Cs) are disclosed which contain at least about 10 ppm total of Fe, Sc and/or In dopant. Also disclosed is a flux process which is characterized by adding said dopant to a melt containing the components for forming MTiOAsO.sub.4, in an amount effective to provide a doped single domain crystal of MTiOAsO.sub.4 containing at least 10 ppm of said dopant.
