Abstract

We have studied possible candidates for laser cooling transitions in 109Tm in the spectral region of 41U-42U nm. By means of saturation absorption spectroscopy, we have measured the hyperfine structure and rates of two nearly closed cycling transitions from the ground state 4 f¹³6s² (²F₀) (J_g = 7/2) to upper states 4f¹²(3H5)5d3/26s2(Je = 9/2) at 410.6 nm and 4f¹²(³F₄)5d_5/26s²(J_e = 9/2) at 420.4 nm and evaluated the life times of the excited levels as 15.9(8) ns and 48(6)ns, respectively. Decay rates from these levels to neighboring opposite-parity levels are evaluated by means of Hartree-Fock calculations. We conclude that the strong transition at 410.6 nm has an optical leak rate of less then 2 x 10^-5 and can be used for efficient laser cooling of ¹⁶⁹Tm from a thermal atomic beam. The hyperfine structure of two other even-parity levels, which can be excited from the ground state at 409.5 nm and 418.9 nm, is also measured by the same technique. In addition, we give a calculated value of 7(2) s^-1 for the rate of magnetic-dipole transition at 1.14 μm between the fine structure levels (Jg = 7/2) ↔ (J'_g = 5/2) of the ground state which can be considered as a candidate for applications in atomic clocks.

Decay rates from these levels to neighboring opposite-parity levels are evaluated by means of Hartree-Fock calculations.

 and can be used for efficient laser cooling of <sup>169</sup>
Tm from a thermal atomic beam. The hyperfine structure of two other even-parity levels, which can be excited from the ground state at 409.5 nm and 418.9 nm, is also measured by the same technique. In addition, we give a calculated value of 7(2) s<sup>-1</sup>
 for the rate of magnetic-dipole transition at 1.14 μm between the fine structure levels (Jg = 7/2) ↔ (J'<sub>g</sub>
 = 5/2) of the ground state which can be considered as a candidate for applications in atomic clocks.</div>
