Quantum Gravimeter

The quantum gravimeter, the first commercial device of its kind in the UK, uses quantum interference of matter waves to measure the local value of gravitational acceleration, or ‘g’, with very high precision. Objects with different mass cause small fluctuations in the value of g measured on the surface of the Earth. The quantum gravimeter can be used to sense these objects hidden under the surface in a non-intrusive manner.

Optical Lattice Clock

M Squared Lasers

Our strontium lattice clock project aims to create the world’s first commercially available fully integrated optical frequency atomic clock. The clock will be compact, transportable, easy to use and based on optical lattice technology enabled by the SolsTiS. The strontium lattice clock will achieve frequency uncertainties below 10-17, a level unprecedented on the global market.

Phase Locked Laser System

SolsTiS-Phase Locked - M Squared Lasers

The phase locked SolsTiS system is primarily designed for use in atom interferometry and quantum computing where Raman transitions are commonly used, although we can tailor the setup to other applications. The system provides extremely low phase noise and high output powers. Full control over the system is provided through our easy to use Ice Bloc user interface.

Rack Mounted SolsTiS System for Cold Atom Experiments

SolsTiS-Rack Mounted - M Squared Lasers

The rack mounted SolsTiS system is designed for the operation of portable cold atom experiments, although it is equally at home in a laboratory where space is limited. The pre-mounted system enables rapid set-up of desired experiments and investigations, minimising downtime due to laser assembly and integration. The system can be customised to your requirements with additional optics packages.

Quantum Accelerometer

M Squared Lasers

A quantum accelerometer uses atom interferometry to measure accelerations along a horizontal axis. Quantum accelerometers are able to achieve a combination of sensitivity and stability by exploiting quantum interference. As such, they will be critical components of a quantum inertial navigation unit, which will offer satellite-free navigation with unparalleled long-term accuracy. A phase locked SolsTiS system underpins this setup and provides the extremely low phase noise required to make high sensitivity measurements and dynamic frequency tunability to address multiple atomic transitions.
