Compact and frequency stabilized laser heads for Rubidium atomic clocks [PDF]

International Conference on Space Optics — ICSO 2012, 2017
We present the development and complete spectral characterization of our compact and frequency-stabilized laser heads, to be used for rubidium atomic clocks and basic spectroscopy. The light source is a Distributed Feed-Back (DFB) laser diode emitting at 780 nm or 795 nm.

New miniaturized microwave cavity for Rubidium atomic clocks [PDF]

2012 IEEE Sensors, 2012
Nowadays there is an increasing need for radically miniaturized and low-power atomic frequency standards, for use in mobile and battery-powered applications. For the miniaturization of double-resonance (DR) Rubidium (87Rb) atomic clocks, the size reduction of the microwave cavity or resonator (MWR) to well below the wavelength of the atomic transition (

The ac stark shift and space-borne rubidium atomic clocks [PDF]

Journal of Applied Physics, 2016
Due to its small size, low weight, and low power consumption, the Rb atomic frequency standard (RAFS) is routinely the first choice for atomic timekeeping in space. Consequently, though the device has very good frequency stability (rivaling passive hydrogen masers), there is interest in uncovering the fundamental processes limiting its long-term ...

Frequency stabilization of multiple lasers to a reference atomic transition of Rb. [PDF]

Sci Rep, 2022
Modern atomic clocks based on the interrogation of an atomic transitions in the optical regions require multiple lasers at different wavelength for producing atomic ions, trapping and laser cooling of neutral atoms or atomic ions.
