Our Optical Reference System (ORS) product family delivers best-in-class phase noise and frequency stability, together with reliable, automated, 24/7 turnkey operation—all this as a readily transportable device. The ORS family offers complete ultrastable laser solutions that provide all the infrastructure required for convenient operation. They are the result of more than a decade of careful engineering driven by our quest for ultimate frequency stability. Menlo Systems’ ORS products are the technical backbone in many of the world’s most demanding applications in the fields of optical clocks, quantum computing, and quantum physics experiments based on cold matter. We configure each system in terms of laser wavelength, power, frequency stability and interfaces such that it is tailored to your needs.
