Characterization of the individual short-term frequency stability of Cryogenic Sapphire Oscillators at the 1e-16 level
Christophe Fluhr, Serge Grop, Benoît Dubois +3
We present the characterisation of three Cryogenic Sapphire Oscillators using the three-corner-hat method. Easily implemented with commercial components and instruments, this metho…
Tests of Sapphire Crystals Produced with Different Growth Processes for Ultra-stable Microwave Oscillators
Vincent Giordano, Christophe Fluhr, Serge Grop +1
We present the characterization of 8-12 GHz whispering gallery mode resonators machined in high-quality sapphire crystals elaborated with different growth techniques. These microwa…
Influence of the ESR saturation on the power sensitivity of cryogenic sapphire resonators
Vincent Giordano, Serge Grop, Pierre-Yves Bourgeois +2
Here, we study the paramagnetic ions behavior in presence of a strong microwave electromagnetic field sustained inside a cryogenic sapphire whispering gallery mode resonator. The h…
Unprecedented High Long Term Frequency Stability with a Macroscopic Resonator Oscillator
Serge Grop, Wolfgang Schäfer, Pierre-Yves Bourgeois +5
This article reports on the long-term frequency stabilty characterisation of a new type of cryogenic sapphire oscillator using an autonomous pulse-tube cryocooler as its cold sourc…
ELISA: a cryocooled 10 GHz oscillator with 10-15 frequency stability
S. Grop, P. Y. Bourgeois, N. Bazin +8
This article reports the design, the breadboarding and the validation of an ultra-stable Cryogenic Sapphire Oscillator operated in an autonomous cryocooler. The objective of this p…
