Role of saturation in the multiphoton transitions

  • É. V. Lugin


The effects of a medium (of collisions) on the probability for two-photon absorption in a three-level system are analyzed. It is shown qualitatively that saturation can occur, under conditions more stringent than for one-photon saturation. A possible mechanism for lowering the population state of the radiation flux during multiphoton ionization is discussed.
