Dispensing and Hermetic Sealing Rb in a Miniature Reference Cell for Integrated Atomic Clocks

Herbert Shea, Peter Ryser, Thomas Maeder, Fabrizio Vecchio, Vinu Lalgudi Venkatraman

An innovative method for filling and sealing the reference cell for a Rubidium (Rb) integrated atomic clock is presented. We used a simple, low-temperature solder sealing technique for producing mini-cells of the size of 12 x 10 x 2 mm, suitable for Rb min ...

Evaluation of the frequency stability of a VCSEL locked to a micro-fabricated Rubidium vapour cell

Yves Pétremand

We present our evaluation of a compact laser system made of a 795 nm VCSEL locked to the Rubidium absorption line of a micro-fabricated absorption cell. The spectrum of the VCSEL was characterised, including its RIN, FM noise andline-width. We optimised th ...

CPT spectroscopy on low-temperature sealed MEMS rubidium vapour cells

Nico de Rooij, Herbert Shea, Thomas Maeder, Yves Pétremand, Frank Seigneur

In recent years there has been a strong effort to reduce the size and power consumption of vapour cell atomic clocks [1,2]. The progress in this direction is driven by several factors such as the use low power laser diodes (VCSEL), Coherent Population Trap ...

Four new noncentrosymmetric salt-inclusion vanadates: (AX)2Mn(VO3)2 (A/X = Rb/Cl, Cs/Cl, Cs/Br) and (CsCl)2Cu(VO3)2

Wendy Lee Queen

Hybrid solids, made of chem. dissimilar components, have drawn much interest in advanced materials synthesis due to their structural versatility and multifunctional properties. For example, metal-org. frameworks (MOFs) have been extensively explored for th ...

The self-hosting structure of beta-Ta

Gervais Chapuis, Alla Arakcheeva

Using electrodeposition from a bath of molten fluorides, single crystals of tetragonal beta-tantalum have been obtained for the first time at normal pressure. The unit-cell parameters are a = 10.211 (3), c = 5.3064 (10) Angstrom, space group P (4) over bar ...

Développement d'un appareillage pour l'étude de la polarisation optique de l'hélium-3 et de sa relaxation par des surfaces

We have developed an apparatus to polarize 3He gas (at a few torrs pressure) by optical pumping from a 4He light source and to measure the evolution of the magnetic moment for relaxation studies. The magnetic moment is measured by applying a pulse of radio ...
