Nd:GdVO4
 

The Czochralski method Nd:GdVO4 is a promising material for diode pumped lasers.
Like neodymium doped yttrium vanadate, the gadolinium vanadate exhibits a larger absorption and emission cross section compared to Nd:YAG. In fact, Nd:GdVO4 has a 7-times higher absorption cross section at 808nm and a 3-times larger emission cross section at 1.06μm than does Nd:YAG. Nd:GdVO4 has the additional advantage over Nd:YVO4 of a much higher thermal conductivity.
