High Energy Laser Mirrors
REO's proprietary superpolishing fabrication and precision IBS coatings provide very low surface scatter, resulting in very highly reflective and enviromentally stable high energy laser mirrors. Reflectivity levels can be above 99.999% and scatter and absorption below 1 ppm at certain wavelengths. These high engery laser mirrors are available with plano or curved surfaces and can be customized for either CW or pulsed laser sytems.

Ion Beam Sputtered Coatings (IBS)
REO pioneered the commercial use of IBS Coatings in the late 1980’s. With 22 IBS systems in operation today, REO is home to the world’s largest concentration of IBS optical coating technology. Our IBS technology produces thin films with exceptionally low scatter and absorption along with high mechanical and environmental durability. Utilizing primarily metal oxide materials, REO uses IBS to produce films which function from the UV through the Mid IR (up to 6um).

Laser Damage Testing
REO provides some of the highest laser damage resistant optics in the world and is committed to the highest possible standard for testing and qualification of these optics. With our own fully automated laser damage test capability, REO not only conducts routing production testing of our products, but also continuously advances the state of the art in understanding laser damage mechanisms and test methodologies.
REO’s primary test system is comprised of a ~20ns pulse length 1064nm laser induced damage threshold (LIDT) test system according to ISO 21254-2 or other similar test protocols.

High Laser Damage Threshold Optics
REO consistently delivers optics with exceptional laser damage resistance characteristics because we fabricate, coat and laser damage test our products under highly controlled processes in our state of the art facility in Boulder, CO. REO is unique because of our broad well-equipped in-house laser damage testing lab with several different laser pulsewidths and wavelengths. This vertical integration is critical because reliably achieving high damage threshold requires careful control over every aspect of the design and manufacturing process. This includes precise specification and thorough inspection of incoming raw materials, followed by shaping and polishing of components in a way that minimizes subsurface damage and contamination. We then design and deposit thin film coatings using techniques that avoid contamination and minimize electric field effects.
