Results on the laser ionization based on resonance saturation (LIBORS) in sodium vapor

Some interesting results on the laser ionization of sodium in thermionic diode based on 3s - 3p resonance saturation (LIBORS) with excimer pumped dye laser are reported. The results are compared with two-color/two-photon ionization where the excimer photon at 308 nm is used as the 2nd photon.
