Diffractive Optical Elements (DOEs) for CO₂-Lasers

Diffractive optical elements (DOEs) are used to shape laser beams or split them into several beams. The physical principle behind this is grating-induced diffraction.

These are substrates with an applied microstructure that generates almost any kind of diffractive effect. The structures manufactured by our partner Holo-OR are generated through a lithographic etching process. The elements can therefore be used in high power laser applications.

In addition to a large assortment of standard elements, our core competence is in the development of custom-made-products. We are able to manufacture special designs according to your wishes.

Depending on your needs, on the wavelength, and on the application in transmission or reflection, the diffractive structures can be produced on the following materials:

• UV-IR in Transmission:
  Fused Silica, CaF₂, Sapphire
• IR in Transmission:
  ZnSe, ZnS, Si, GaAs
• IR in Reflection:
  Cu, Si, Chrome
