Magnesium oxide(100)＆(110)Orientation MgO Single Crystal substrates
by size 10x10x0.5mmt or 2inch x0.5mmt /2'' inch Gadolinium gallium
garnet GGG (Gd3Ga5O12) crystal substrate
Crystal Substrates Gallium Gadolinium Garnet Gd3Ga5O12 GGG single
crystal
Gallium Gadolinium Garnet (Gd3Ga5O12 or GGG) single crystal is
material with good optical, mechanical and thermal properties which
make it promising for use in fabrication of various optical
components as well as substrate material for magneto – optical
films and high – temperature superconductors.It is the best
substrate material for infrared optical isolator (1.3 and 1.5um),
which is a very important device in optical communication. It is
made of YIG or BIG film on the GGG substrate plus birefringence
parts. Also GGG is an important substrate for microwave isolator
and other devices. Its physical, mechanical and chemical properties
are all good for the above applications.
