BEECH - ULTRA LOW DRIFT OPTICAL REFERENCE FOR QUANTUM APPLICATIONS

BEECH – ULTRA LOW DRIFT OPTICAL REFERENCE FOR QUANTUM APPLICATIONS

Simultaneous frequency stabilisation of 4 lasers with sub MHz long-term drift rates in a rack mounted device. BEECH fits perfectly inside a standardized 19-inch rack.

Reliable and accurate frequency stabilisation of lasers is key for quantum optics and quantum information experiments with trapped ions or atoms. BEECH offers frequency stabilisation of 4 key wavelengths for trapping 40Ca+ in a single 4 RU, 19-inch rack module. Ultra low drift rates and full remote control ensure high reproducibility with minimum effort.

Frequency stabilisation of lasers can take a significant amount of work and space in the lab.

With our fully digital, fiber coupled BEECH you won’t have to worry about wavelength calibration anymore. Wavelengths will stay where you need them and the BEECH can be stored in a 19-inch rack, freeing valuable space on the optical table.

Stabilization of four key experimental wavelengths for 40Ca+ trapping
Stabilisation of four key experimental wavelengths for 40Ca+ trapping.

Frequency stabilisation of lasers at vastly different wavelengths may generate a lot of overhead in space and effort. Our compact BEECH simultaneously stabilises lasers at 397 nm, 423 nm, 854 nm and 866 nm for 40Ca+ trapping.

Ultra low linear drift of 4.8 kHz per day
Ultra low linear drift of 2.4 kHz per day.

The ultra low linear drift of BEECH guarantees constant performance of your experiment and reduces calibration overhead.

BEECH utilizes fully digital signal processing. Operated via a web-based graphical user interface, it is perfectly suited for remote operation and service.

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.
