Abstract

Abstract: We demonstrate a simple and efficient readout procedure of the 1.14^m clock transition excitation efficiency in neutral thulium atoms. Our method utilizes additional but short clock n-pulse to measure number of atoms excited by spectroscopic clock pulse, that allows to determine excitation probability insensitive to fluctuation of number of atoms in the trap. It is important that this method can be used for both hyperfine components of the clock transition and does not require any additional lasers in the setup.
