Passivation & Coating of Laser Facets

We passivate GaAs laser facets using our patented process. This enables both a high output power and a high long-term stability of the lasers.

After the passivation process we additionally realize facet coatings for reflectivities in the range of 0.05% to 98% upon request.

Here you can find more information about technologies and processes we use for the production of our gallium arsenide laser diodes.

Metallic component made from several layered plates. The surface is shiny and the parts appear to be precisely joined together. An inscription with the letters “FBH CC 00140” is visible on the side.
