Description
The Optical Reference System (ORS) consists of a fiber laser locked to a stable high‐finesse cavity made of ultralow 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.
Feature
- ultra high-finesse cavity (spacer and mirrors) made out of ultra low expansion glass
- temperature stabilization of the cavity
- complete conflat flange sealed UHV system
- mechanical transport lock which allows for setting up and moving the system without optical readjustment
- active vibration isolation platform
- acoustic isolation
- polarization maintaining cw laser
- stabilization of optical power
- SYNCRO lockbox using the Pound-Drever-Hall locking scheme
Related Applications
- ultra high precision spectroscopy
- low noise RF generation
- interrogation of optical clocks
- metrology
