A five-year record of the lockpoint frequency of a Zeeman stabilized laser shows an observed drift rate of 0.3 ± 0.5 MHz/yr following an initial drift of 5.7 ± 2.2 MHz/yr in the first eighteen months of intermittent operation. A second Zeeman laser drifted at a rate of −0.8 ± 1.0 MHz/yr over the last 2.5 yr; the frequency drift was −0.2 ± 0.6 MHz/yr over the last 3.3 yr. Empirical temperature corrections to laser frequency measurements produce a slight variance reduction in the data but no effective bias in the drift estimates.
