New Measurement of the 2S Hyperfine Interval in Atomic Hydrogen
N. Kolachevsky, A. Matveev, J. Alnis +3
An optical measurement of the 2S hyperfine interval in atomic hydrogen using two-photon spectroscopy of the 1S-2S transition gives a value of 177 556 834.3(6.7) Hz. The uncertainty…

Sub-Hz line width diode lasers by stabilization to vibrationally and thermally compensated ULE Fabry-Perot cavities
J. Alnis, A. Matveev, N. Kolachevsky +3
We achieved a 0.5 Hz optical beat note line width with ~ 0.1 Hz/s frequency drift at 972 nm between two external cavity diode lasers independently stabilized to two vertically moun…
