✦ Synopsis
When an unfocused laser beam with narrow linewidth whose frequency matches exactly an atomic transition line of the Fe atom was passed through a gas mixture containing Fe(CO)5, atomic emissions from the state-selected excited state of Fe atoms were observed. The power dependence of the emission intensities as well as excitation and fluorescence spectra suggested that the state-selected excited state Fe atoms are generated by one-photon absorption of the ground state Fe atoms formed by two-photon dissociation of Fe(CO) 5 within a single laser pulse.
