13. The measured internal windows reflection follows a low-finesse Airy function, measured as a ratio with the reflection coefficient of the outer window. Scattering losses attenuate the expected peak value by less than 5%. Due to the 3-wavelength measurement, a high sensitivity is obtained because, for at least one wavelength, the slope of the Airy function exhibits a large value. Note that further experiments on an analogous sapphire cell have shown that the scattering losses can seriously impair the cell thickness evaluation.
14. This is a consequence of the choice of using thick YAG windows. Further cell technology developments show that, with thinner windows, the local thickness can be temperature-controlled; it can also be made tuneable with a variable external pressure. Note also that, when increasing temperature, we observed an increase of scattering losses, probably due to some Cs layer.
