AMDCrystals

We are a new company engaged in the cultivation and sale of optical nonlinear and laser crystals.

You haven't heard of us yet. But, our crystal growing specialists are known all over the world and have more than 30 years of experience in this field.

We own the technology of growing many chalcogenide crystals.

For example, crystals AgGaS2, AgGaSe2, GaSe, previously grown by members of our team, have established themselves as standards of the best world quality.

We can also offer you new unique nonlinear crystals based on Ba. Such as: BaGa4S7, BaGa4Se7, BaGa2GeSe6, BaGa2GeS6, Ba2Ga8GeS16 at the lowest prices, since we are their manufacturer.
