-Stressed compensated (SC) cut led recently to the best frequency stability ever obtained with a quartz oscillator, 2.5 · 10 À14 for the flicker frequency modulation (FFM) floor. This result is confirmed in this paper with a 3.2 · 10 À14 ± 1.1 · 10 À14 . The quartz resonator is integrated in a 5 MHz enhanced aging box double oven controlled oscillator. After reminding a bit of history, this paper describes how the first significant development in terms of ultra-stable quartz state-of-the-art oscillators was performed in the last 20 years, how the resonators were chosen, and main information about the development of adequate electronics and how to mechanically and thermally stabilized such an ultra-stable oscillator. We also present how to characterize the expected performances, and hot topics in quartz based oscillators.

“…For this uncertainty estimation, we use a similar method like in optics [19 -21] and microwaves [22,23] based on the requirement delivered by GUM. Frequency references of the 5 MHz or 10 MHz type possibly ensures the traceability of the BLS method to national standards [24,25]. One contribution is due to the laser beam and the axis of displacement, which are not exactly parallel [26,27].…”

Inelastic scattering of light by acoustic waves from a medium are known as Brillouin scattering. This effect was demonstrated by Léon Brillouin. Laser beam with high power enables Brillouin scattering thanks to acoustic vibrations in polymethyl methacrylate (PMMA). This phenomenon is known as stimulated Brillouin scattering. In our case we use a commercial bench based on the J. R. Sandercock multipass tandem interferometer design. Our study aims to gain confidence in knowing if the result given by the bench can lead to a more precise determination of the order of magnitude of the uncertainty associated with the result obtained in terms of deviation to the optical carrier. We determine the uncertainty to be ± 0.26% at 2 σ based on a modern approach. We intend to present it at the conference to give indications on the expected uncertainty terms of the microwave signal deviation of the carrier at 532 nm, characterising PMMA.

“…Frequency references of the 5-MHz or 10-MHz type ensure the frequency traceability of the BLS measurement system to national metrology standards [ 88 , 89 ]. It is then possible to have the best reference in terms of frequency stability to connect them to additional measuring devices, such as oscilloscopes or other frequency measurement instruments.…”

The expanded uncertainty of the measured Brillouin scattering shift frequencies is essential in assessing the measurements of parameters of various materials. We describe the general operation principles of a Brillouin light scattering (BLS) spectrometer with a high-power laser and a scanning tandem Fabry–Pérot interferometer (TFPI) for material characterization. Various uncertainty components have been analyzed for the BLS spectrometer following the Guide to the Expression of Uncertainty in Measurement (GUM). The expanded relative uncertainty in the measured Brillouin frequency shift of 15.70 GHz for polymethyl methacrylate (PMMA) was estimated to be 0.26%. The calculated Brillouin frequency shift (based on material properties of PMMA) was determined to be 15.44 GHz with expanded relative uncertainty of 2.13%. It was shown that the measured and calculated Brillouin frequency shifts for PMMA agree within their expanded uncertainties. The TFPI-based BLS spectrometer can be used to measure the longitudinal modulus of materials with an expanded uncertainty of 1.9%, which is smaller than that of the ultrasonic velocity-based method (estimated to be 2.9%).
