Abstract

We report advances towards the development of frequency standards based on narrow two-photon transitions in the silver atom at 576 and 661 nm from the ground 4d¹⁰5s²S_1/2state to the ²D_3/2,5/2levels of the configuration 4d⁹5s². We describe detection schemes for metastable atoms, localisation of the position of the metastable ²D_5/2level and diode-pumped Nd:YLF lasers around 1.3 μm destined to replace dye lasers for both cooling and spectroscopy of the clock transition. Our result for the position of the ²D_5/2level is more than a factor of two improvement over previous vales.
