Application
The
yttrium vanadate(YVO4)grown by method of Czochralski is a positive
uniaxial crystal, with excellent mechanical and optical properties.
It has a very wide transparency range with high transmittance
and large birefringence. Therefore, it is an ideal material for
the field of fiber optics, including fiber optic isolators and
circulators, beam displacers, glan polarizers and so on.
MgF2 crystal is a excellent material for the field of fiber optics,
with its properties of wide transparency range and high birefringence.
