We demonstrate a miniaturised and highly robust system for performing Doppler-free spectroscopy on thermal atomic vapour for three frequencies as required for cold atom-based quantum technologies. The application of additive manufacturing techniques, together with efficient use of optical components, produce a compact, stable optical system, with a volume of 0.089 L and a weight of 120 g. The device occupies less than a tenth of the volume of, and is considerably lower cost than, conventional…

Ultrastable, Zerodur-based optical benches for quantum gas experiments.

Zerodur-based optical systems which include single-mode fiber couplers consisting of multiple components jointed by light-curing adhesives are reported on, revealing excellent fiber-coupling efficiencies between 0.85 and 0.92 in the temperature range from 17°C to 36°C.

Dual-frequency spectroscopy for compact systems and enhanced laser stabilisation

Vapour-cell spectroscopy is widely used for the frequency stabilisation of diode lasers relative to specific atomic transitions — a technique essential in cold atom and ion trapping experiments. Two

Ultrastable assembly and integration technology for ground- and space-based optical systems.

A novel adhesive bonding technology for setup of quasi-monolithic systems is presented and selected characteristics are compared to the well-established state-of-the-art technique of hydroxide-catalysis bonding to achieve an equivalent passive path length and tilt stability.

Prototype of a compact rubidium-based optical frequency reference for operation on nanosatellites

Space-borne optical frequency references based on spectroscopy of atomic vapors may serve as an integral part of compact optical atomic clocks, which can advance global navigation systems, or can be

Practical system for the generation of pulsed quantum frequency combs.

This work introduces an actively-modulated, nested-cavity configuration that exploits the resonance pass-band characteristic of the micro-Cavity to enable a mode-locked and energy-efficient excitation, and allows the generation of high-purity photons at large coincidence-to-accidental ratios (CAR).

Spectroscopy of cold rubidium Rydberg atoms for applications in quantum information

Atoms in highly excited (Rydberg) states have a number of unique properties which make them attractive for applications in quantum information: large dipole moments, lifetimes, and polarizabilities,
