Description
Following the methods developed for atom ionization by alternating electric field
the probability of multi-photon absorption of photons of the strong external laser field by channeled electron (ejection of electron from the channel, photo-ionization) have been calculated for different strengths of the external field and different levels of electrons in a planar channel. The emission spectra of 54 MeV electrons channeled in diamond crystal planes (110) are shown for different values of the resonant laser control field of a frequency close to the transition frequency in the channel with and without photo-ionization. It is shown that the ionization probability is less than the probability of electron scattering in the crystal and make a small contribution to the total level width.
