  • We propose to use the magnetic-dipole transition at = 1.14 m coupling two ground state fine-structure components of thulium (Tm), as a 'clock transition' in optical clocks. We have demonstrated first stage laser cooling of Tm atoms down to a temperature of 25 K using a strong transition at = 410.6 nm and we have also shown preliminary results for second stage cooling using a weaker transition at = 530.7 nm (natural linewidth G =350 kHz). Laser cooled atoms have been trapped in an optical dipole trap and in a 1D optical lattice operating near 532 nm. 2014 Astro Ltd.
