"people don't appreciate 1e-18 fractional accuracy enough. It took decades of development pushing many things to the extreme. For example let's take a look at the optical cavity used for stabilizing the laser used for these atomic clocks. The most recent fight they had with the cavity is replacing the dielectric coating (sputtered SiO2/Ta2O5 or TiO2) which is amorphous to stacks of crystalline GaAs/AlGaAs because crystals have lower thermal mechanical noise than amorphous materials and they got a cavity with 2.5e-17 stability with such quieter mirror coatings.

"here are the results from claude it picked Sellmeier equation to model the wavelength dependency of BTO's refractive index even without explicit ask (good bot) and I asked it to calculate both the ellipsometry results (left should look very familiar to you if you've done it) as well as the reflection spectrum (right). The ellipsometry angles are chosen to be around the brewster angles because you'll see it blow up and be sensitive to film thickness. The reflectance is calculated near the actual angle where the photo was taken from the aspect ratio of the wafer."
