Custom AR (Anti-reflection) Coating Services for Laser Crystals

At Design Realized, we provide custom anti-reflection (AR) coating services for a wide range of laser crystals and optical components used in scientific research, industrial lasers, medical systems, and prototype photonics development.

Our coating services are suitable for both standard and custom crystal geometries, including rods, wafers, disks, windows, and precision-polished optics.

What is AR Coating?

Anti-reflection (AR) coating is a thin-film optical coating applied to crystal or optical surfaces to reduce reflection losses and improve transmission efficiency at specific wavelengths.

Proper AR coating can significantly improve:

Laser output efficiency
Optical transmission
Beam quality
Power stability
Damage threshold
Overall system performance

For laser systems, even a few percent improvement in transmission can make a major difference in efficiency and thermal performance.
