Measurement of the ${}^{20-22}$Ne ${}^3$P${}_2$-${}^3$D${}_3$ transition isotope shift using a single, phase modulated laser beam

Abstract

We develop a simple technique to accurately measure frequency differences between far lying resonances in a spectroscopy signal using a single laser. This technique was used to measure the isotope shift of the cooling transition of metastable neon for the result of $1626.264(79)$ MHz. The most accurate determination of this value to date.
