Abstract
Cavity-mode wavelengths in air are determined by measuring a laser's fequency while it is locked to the mode in vacuum during a caibration 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 plus or minus}2 X 10-8(3ς), with the wavelength accuracy limited to plus or minus}4 X 10-8 by knowledge of the absolute helium gas temperature during the pressure calibration. Mirror cleaning perturbed the mode frequncy by less than Δ}Ņ/Ņ 3 X 1010-9, limited by temperature correction residuals.Citation
