Description
The Optical Reference System (ORS) delivers an optical output with ultra narrow linewidth and outstanding short term stability. It consists of a cw laser locked to a stable high-finesse cavity made of ultra low expansion (ULE) glass. The compact design allows for integration of the vacuum chamber, control electronics, vibration isolation platform and acoustic isolation into a 19” rack system and delivers state-of-the-art laser linewidth and stability. Additionally, the system design includes a mechanical locking feature which allows for transportation of the system without the need to readjust the beam coupling into the cavity, once the mechanism is disengaged. Every system is fully characterized at Menlo Systems before shipment. The characterization is carried out either against a reference system with equal or better performance, or in a three cornered hat comparison.
