In the fields of precision and innovation, one component stands out—the output coupler (commonly referred to as the output coupler in a resonator). By simultaneously reflecting and transmitting a predefined ratio of light based on the properties of the laser gain medium, it serves as a core optical element in countless lasers and their applications.OPTOMAN utilizes Ion Beam Sputtering (IBS) coating technology, an inherently stable process that enables the production of optical components with extremely precise reflectance and transmittance specifications. Furthermore, as an intracavity component, the output coupler must withstand extreme energy densities. For this reason, OPTOMAN coatings are optimized for high laser damage thresholds to ensure durability and long-term stability.
Whatever your laser application needs may be, at WAVEQUANTA you can find the precise optical components you require.
Notes:For optimal performance, store and use at 25 °C and 40%–60% relative humidity. If contamination occurs on the coated surface, gently clean with >99% isopropyl alcohol and lint-free lens tissue. Avoid using rough fabrics, water, or abrasive cleaners, as these may damage the coatings.
