Product Description
High-precision output coupler (OC) mirror for Ruby laser resonant cavities operating at 694 nm. The coating provides approximately 74% reflectivity at the Ruby laser wavelength.
The lower reflectivity compared with high-reflectivity cavity mirrors allows stronger output extraction from the resonator. The rear surface has an anti-reflection (AR) coating to reduce internal losses and unwanted ghost reflections.
The mirror is made on a Schott BK7 optical glass substrate and is suitable for experimental Ruby laser systems, pulsed laser resonators and laboratory optical setups.
