We report on accurate measurements of the scalar αS and tensor αT polarizabilities of the 5D fine structure levels 5D 3/2 and 5D 5/2 in Rb. The measured values (in atomic units) αS(5D 3/2 ) = 18400(75), αT (5D 3/2 ) = −750(30), αS(5D 5/2 ) = 18600(76) and αT (5D 5/2 ) = −1440(60) show reasonable correspondence to previously published theoretical predictions, but are more accurate. We implemented laser excitation of the 5D level in a laser cooled cloud of optically polarized Rb-87 atoms placed in a constant electric field.

Recently, the thulium atom was cooled down to the Bose-Einstein condensation temperature, thus opening a pathway to quantum simulation with this atom. However, successful simulations require instruments to control and readout states of the atom as well as the ability to control the interaction between either different species or different states of the same type of species. In this paper, we provide an experimental demonstration of high-fidelity (over 93%) manipulation of the ground state magnetic sublevels of thulium, which utilizes a simple and efficient design of a microwave (MW) antenna. The coherence time and dephasing rate of the energetically highest hyperfine level of the ground state were also examined.

Frequency stabilization of a diode laser on the 5P→ 5Dtransition of the Rb atom

et al. 2017

In this work, we investigated the frequency stabilization method of a diode laser that operates on the excited state transition → P D 5 5 of Rb atoms. The described technique allows simple control of the diode laser frequency stabilization to be performed. The critial parameters of stabilization, such as laser intensity and the temperature of a reference cell, have been investigated and long-time laser stability has been demonstrated with frequency stability of about 1 MHz.
