Product Description
High-quality ruby laser output coupler (OC) mirror designed for 694 nm ruby laser resonators. With approximately 85% reflectivity and 15% transmission at 694 nm, this mirror is especially suitable for pulsed free-running ruby laser operation.
The mirror is built on a precision Schott BK7 optical glass substrate. The output-coupler coating is a dielectric PVD multilayer, while the second face has an antireflection (AR) coating to reduce secondary reflections and internal interference.
- Output coupler for ruby laser cavities at 694 nm
- R ~85% / T ~15% balance for free-running pulsed operation
- 25 mm diameter BK7 substrate, 8 mm thickness
- AR coating on the second face
- Suitable for laboratory setups, laser repair, restoration and experimental resonators
