Abstract

Cavity-mode wavelengths in air are determined by measuring a laser’s frequency while it is locked to the mode in vacuum during a calibration step and subsequently correcting the mode wavelength for atmospheric pressure compression, temperature difference, and material aging. Using a Zerodur ring cavity, we demonstrate a repeatability of ±2 × 10−8 (3σ), with the wavelength accuracy limited to ±4 × 10−8 by knowledge of the absolute helium gas temperature during the pressure calibration. Mirror cleaning perturbed the mode frequency by less than Δν/ν ∼ 3 × 10−9, limited by temperature correction residuals.
