We present the characterization of a prototype surface-electrode (SE) trap as a first step towards the realization of a compact, single-ion optical clock based on Yb$^+$. The use of a SE trap will be a key factor to benefit from clean-room fabricatio

In this work, we present a technique to control and reduce the residual amplitude modulation (RAM) in the cavity-stabilized laser, which is one of the main limitations of these systems. The RAM rises from polarization mismatch between electro-optic m

International audience; We present an ultra-stable laser based on a compact Fabry-Perot cavity with a thermal noise limit expected at 2 × 10 15 in trems of fractional frequency stability. The 25 mm long cavity is housed in a cubic vacuum chamber wit

Publikováno v: OSA Continuum. 3:50

The ytterbium atom is widely used in the fields of atomic physics, cavity quantum electrodynamics, quantum information processing, and optical frequency standards. There is however a strong dispersion among the reported values of the 1S0 → 1P1 tran

International audience; The use of a high Finesse Fabry-Perot cavity emerged in the last centry as a way to stabilize the frequency of a laser source fundamental for atomic optical clocks. The improvement of such cavities also has a major stake for a
