The magnetic dipole transition between fine structure sublevels of the ground state of thulium atom 4f{sup 13}({sup 2}F{sup o})6s{sup 2} has been directly excited in a cloud of ultra-cold atoms by a frequency-stabilised laser. This transition at the wavelength λ = 1.14 μm is planned to be used as the clock one in an optical frequency reference on laser-cooled thulium atoms. (extreme light fields and their applications)
