Description

Multi-photon ionization of excited states of He or Hg atoms in glow discharge tube by ruby laser light were detected by using the induced variation of discharge current. The probabilities of one-photon, two-photon and three-photon ionizations with an intermediate resonance were also calculated. Laser induced current variation was explained by the calculated value of multi-photon emitted electrons. It was found that two-photon resonant three-photon ionization is dominant in He and three-photon ionization in Hg in case of rather high intense laer light. (author)
