Abstract
Spectroscopy of the rubidium 5P3/2 ~ 4D5/2 transition near 1.529 μm has been performed using a single-longitudinal-mode erbium-doped fiber laser. Rubidium atoms were laser-cooled and confined in a vapor-cell Zeeman optical trap. This produced a dense sample of cold atoms and reduced the Doppler broadening of the transition to less than the natural linewidth. Transition linewidths of 10 MHz were observed on the 5P3/2 ~ 4D5/2 transition and the fiber laser was actively stabilized to the 5P3/2, F=3 ~ 4D5/2, F' =3 line of 87Rb.
