Flat, spherical or wedged configuration. Output Couplers are available in pretty much any kind of configuration: flat, plano/convex or plano/concave, meniscus, wedged etc.
Low absorption UV or IR grade fused silica. Bulk absorption plays critical role in a duty cycle of cavity optics. Substrates for Output Couplers are made of application-optimized low absorption fused silica.
Optimized for ultrafast applications. Ultrafast output couplers feature negligible GDD, both in reflection and transmission.
Optimized for high power applications. Output couplers, as intracavity components, have to handle extreme energy densities. That is why these coatings are optimized for high damage threshold, which exceeds 50 J/cm2, 1064 nm, 20 ns.
Back surface AR coated to eliminate ghosting. Back surface is anti-reflective coated, where residual reflectivity is lower than <0.05%. AR coating eliminates parasitic reflections from back surface.
Flat, spherical or wedged configuration.
Single wavelength or broadband design.
Reflectance from 10% up to 99.9% with +/-0.05% accuracy.
Optimization for ultrafast applications.
Diameter from 5mm up to 101.6mm.
Spectral range from 200nm to 6000nm.
