Compact, laser-cooled atomic clocks

Compact, laser-cooled atomic clocks Atomic clocks are a shining example of the power that technology based on atomic physics can have. In the last decades, using atoms laser cooled to the microKelvin regime, the sensitivity of atomic clocks has increased to now being better than one second over the age of the universe.

Ultra-precise atomic magnetometry for unshielded measurements

Ultra-precise atomic magnetometry for unshielded measurements This project builds on the experience at the University of Strathclyde in developing atomic magnetometers with sensitivities better than 1pT. Using compact, room temperature, atomic samples the new lab will compete directly with superconducting quantum interference device (SQUID) based systems that require prohibitively expensive cryogenic environments.

Vapour cells for spectroscopy

Vapour cells for spectroscopy Vapour cells are used in spectroscopic instruments and gas analysers for validation or calibration and for stabilisation. Cascade Technologies has an interest in all of these methods and is particularly interested in developing inexpensive vapour cells for gases with spectral features in the NIR and MIR wavelength regions.
