Product Description
Matched pair of high-reflectivity dielectric mirrors for Ruby Laser (694 nm) resonant cavities. The set includes one HR mirror and one OC output coupler, intended for high-energy pulsed operation in free-running ruby laser configurations.
Both optics are manufactured on Schott BK7 optical glass substrates. The dielectric PVD coatings are optimized around the ruby laser emission wavelength and are suitable for experimental resonators, replacement cavities and laboratory optical setups.
