Laser Crystal Coatings Deliver Exceptional Stability and Lifetime

Produced primarily using ion beam sputtering (IBS) technology, these coatings demonstrate a unique combination of long lifetime, environmental stability, high laser damage threshold, excellent optical performance and superior mechanical durability. When combined with REO’s suite of specialized crystal pretreatment and handling protocols that maximize yields, these thin films enable laser manufacturers to minimize component costs, while also delivering products that exhibit better lifetime and improved performance.

A primary advantage of IBS technology is that it creates fully densified coatings. These non-porous coatings are immune to moisture absorption during operation, extending their lifetimes and preventing shifts in coating performance with changes in ambient humidity. IBS coatings are also very mechanically durable, enabling them to be repeatedly cleaned. In addition, these dense thin films contain fewer defects than other coating types, thus maximizing laser damage resistance. Finally, IBS technology enables greater precision and repeatability during deposition, which permits the production of very consistent coatings, including films with complex, multi-wavelength spectral performance.
