    Springer
    Applied physics 5 (1974), S. 109-115

    Keywords: Isotope separation ; Two-step excitation ; Calcium spectrum ; Autoionization
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Abstract The isotope specific two-step photoionization of metastable Ca atoms was investigated using a continuous wave dye laser and an Ar+ laser. The photoionization was performed via a transition to an autoionizing state. Therefore an ionization probability as high as 10−2 could be obtained.

    Two-photon resonant four-wave mixing in atomic sodium vapour (1978)
    Springer
    Applied physics 15 (1978), S. 427-432 
    Details
    ISSN: 1432-0630
    Keywords: 42.65 C

    Notes: Abstract Using the 4d- and 5s-states of sodium, two different types of two-photon resonance enhanced four-wave mixing have been observed. In the first type 2v L =v IR +v pIR radiation near 2.34 μm and UV radiation near 320 nm has been detected. In the second typev P −v S =v L +v IR the UV radiation produced in the first parametric process acted as a pump for stimulated electronic Raman scattering via the 4p-state of sodium. Resonantly enhanced by the two-photon transition 3s–4s, radiation near 1.18 μm was produced in this scheme. The realisation of a tunable coherent IR source based on these four-wave mixing processes is discussed.
