Description

The Optical Reference System (ORS) 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 high vacuum, temperature stabilization, vibration and acoustic isolation into a 19” system while delivering 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.
