Introduction
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.
