Resolutely turned towards industry, it serves as the interface between the research conducted by FEMTO-ST and the need for innovation in industry. FEMTO Engineering thus offers specific and high-level developments based on the research conducted at FEMTO-ST.
Our work on the field of cryogenic oscillators was initiated 20 years ago, in the former Laboratoire de Physique et de Métrologie des Oscillateurs (LPMO) which becomes the Time and Frequency Department of the Femto-ST Institute at its creation in 2004. The cryogenic sapphire oscillator development in our laboratory has been successively supported by the space French agency (CNES), the DGA, the LNME and the Région of Franche-Comté. This activity gave rise to number of original results described in the bibliography.
The ELISA project funded by ESA represents the outcome of all these efforts: the objective set by ESA was plenty fulfilled and we demonstrated for the first time the possibility to use a cryocooler while maintaining a state-of-the-art frequency stability.
ULISS is the new generation of CSO, specially designed to be transportable and incorporating newly developed electronic controls.
