    In spectroscopy: Basic energy considerations

    With certain pulsed lasers, the two-photon RIS process can be saturated so that one electron is removed from each atom of the selected type. Furthermore, ionization detectors can be used to sense a single electron or positive ion. Therefore, individual atoms can be counted. By taking advantage of tunable laser…
