Abstract

We discuss the multiple peaks observed in the energy spectrum of electrons resulting from multiphoton ionization of atoms by lasers. When the laser intensity is large enough for the ponderomotive force to result in appreciable broading of the peaks we show that the shape of the broadened peaks contains useful information. We show the multiphoton ionization probability as a function of laser intensity can be obtained but that the free-free cross sections which are in principle also obtainable are probably not obtainable in practice.
