Spectroscopy of the 1001 nm transition in atomic dysprosium

Abstract

We report on spectroscopy of cold dysprosium atoms on the $1001\mathrm{nm}$ transition and present measurements of the excited state lifetime which is at least $87.2(6.7)\mathrm{ms}$ long. Due to the long excited state lifetime we are able to measure the ratio of the excited state polarizability to the ground state polarizability at $1064\mathrm{nm}$ to be $0.828(0.129)$ by parametric heating in an optical dipole trap. In addition we measure the isotope shifts of the three most abundant bosonic isotopes of dysprosium on the $1001\mathrm{nm}$ transition with an accuracy better than $30\mathrm{kHz}$.
