Postdoctoral positions available at NIST Boulder.

The Atomic Devices and Instrumentation Group at NIST currently has openings for one or more post-doctoral research associates with a background in atomic physics, laser science or photonics. Projects include MEMS alkali cell fabrication, atomic magnetometry, high-performance compact clocks, atom interferometers and other compact and chip-scale instruments. Non-US citizens are welcome. More information on the NIST ADI group can be found at More information here. Applicants may send a cv and cover letter to John Kitching.

Time-Frequency Research Engineer position available at UAR THETA, Besançon.

This position is offered by CNRS internal mobility, FSEP (Fonctions Susceptibles d’Etre Pourvues), and therefore reserved exclusively for CNRS agents (civil servants and  permanent contract). It will be published on the CNRS website (https://mobiliteinterne.cnrs.fr/afip/owa/consult.accueil) between December 6 and January 17. See the job description for more details Profil_IGR_TF_FSEP_UAR_THETA_3245. For any additional information, please contact the director of the unit: Philippe Rousselot.

18 months Postdoctoral position available in the OHMS team at FEMTO-ST (Besançon, France) to study a new generation of ultra-stable optical Fabry-Perot cavity.

The aim of this work is to study a new generation of ultra-stable optical Fabry-Perot cavity. Such a cavity, made from single crystal silicon maintained below 1 K, will be used as the frequency reference for an ultra-stable laser. It will pave the way for the next generation of ultra-stable lasers with fractional frequency stability lower than 10-17.
As a first step, the Fabry-Perot cavity will be placed and cooled down in a dilution cryostat. A laser source will be frequency-locked to the cavity in order to access its optical properties. Refine measurement of those properties is the second step. The last step will focus on performances characterization to demonstrate the potential of this ultra-low temperature reference.
