  Combined potential of an atom and a uniform laser field. At distances r<r0, the potential of the laser can be neglected, while at distances with r>r0 the Coulomb potential is negligible compared to the potential of the laser field. The electron emerges from under the barrier at r=Rc. Ei is the ionization potential of the atom.

  Feynman diagram for the process of double ionization in an atom through re-scattering mechanism.
• 
  The schematic presentation of lambda type population trapping. G is the ground state of the atom. 1 and 2 are two degenerate excited states. After the population is transferred to the states due to multiphoton resonance, these states are coupled through continuum c and the population is trapped in the superposition of these states.
• Spectrum of Xe at a pressure of 10 Torr using long pulses (5 ns, Nd:YAG laser) with an energy of 100 mJ/pulse and short pulse (200 fs, Ti:Sapphire laser) with an energy of 40 mJ/pulse. The strong line broadening in the case of long pulses is evident.
