BEECH is a fully digital, rack compatible laser frequency stabilisation module for up to 4 different wavelengths. With its compact 4RU 19-inch rack form factor, ultra low frequency drift rates and full remote operation it enables high reproducibility of experimental results with low overhead in space and effort.
BEECH is based on a transfer lock with a proprietary cavity design, thus combining the excellent long term stability of an atomic resonance with the flexibility and short term stability provided by high bandwidth PDH stabilisation to an optical cavity.
It features fiber coupled input ports and a fiber coupled optical reference output at 335.111370 THz for calibration of external devices.
BEECH versions for different atom or ion species available on request.
We’d love to hear from you!
