Abstract For the interpretation of the experiment, where electron beams are modulated at transmission of a laser‐illuminated solid, transferring and generating photons at nonluminescent targets, a simple interaction of electron waves with energies changed by discrete numbers of photons can be assumed. It is concluded that this interaction involves coherence effects of electrons. The coherence length at the conditions of the experiment is of the order of 10 −4 cm. The consequences of measuring these coherence effects are discussed with respect to analyse the interaction effect in the crystal, to study free electron beams at electronoptical modifications, and to examine possible coherence effects of electrons at or before emission from solids.
