Laser Crystal Coating
REO provides thin film coating services on crystals used in a range of
laser applications including gain crystals, nonlinear crystals, q-switches,
and more. These coatings utilize REO’s proprietary Ion Beam Sputtering
process to produce fully densified films for ultra-low-loss and superior
environmental stability. Sophisticated tooling techniques precisely
control the clear aperture and minimize overspray, and proprietary
cleaning technology, crystal pretreatment processes and handling
protocols maintain high yields for customer furnished materials.
