Laser Crystal Coatings Deliver Exceptional Stability and Lifetime


High performance thin film coatings for a wide range of intracavity nonlinear and gain crystal materials

REO, a leading manufacturer of high volume precision optical solutions, now offers thin film coating services for a wide range of customer furnished laser gain and nonlinear crystals, including doped YVO4, doped YAG, doped YLF, doped phosphate glass, doped YSGG, Ti:Sapphire, KTP, LBO, BBO and SBBO.  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. 

REO produces high precision thin film coatings, optics and opto-mechanical assemblies for the ultraviolet, visible and infrared. Located in Boulder, CO, the company primarily services medium to high volume OEMs including manufacturers of defense and aerospace systems, laser systems, semiconductor tools, medical systems, life sciences instrumentation and telecom equipment.  REO is a privately held company.  For more information, contact Mark Damery, Vice President and General Manager of Worldwide Sales, at +1-720-562-3213, e-mail MarkD@reoinc.com, www.reoinc.com, or Susan Anway, Vice President of Finance and Chief Financial Officer at +1-720-562-3206, e-mail SueA@reoinc.com.
