Nd:YAG - Neodymium-doped Yttrium Aluminum Garnet

Electro-Optics Technology GmbH has been growing Nd:YAG for over 20 years. During this time, material properties and qualities have improved to make it one of the best solutions on the market. You will find our material to have lower absorption and higher transmission than are commonly found on the market. EOT GmbH specializes in controlling the dopant level to optimize your pumping requirements. Our high quality Nd:YAG is a highly effective laser medium for high power lasers. 

With over 20 years of polishing and fabrication experiece, EOT GmbH has become a world leader in providing 2D and 3D crystal designs. We also offer low absorbing, high damage threshold optical coatings.
