Generation of electromagnetic fields in the course of emission of electrons from metal target surfaces subjected to laser radiation

A theoretical study is made of the generation of electrical and magnetic fields in the course of electron emission from the surfaces of conducting targets. The emission is due to the photoelectric effects under the action of the radiation emitted from a jet formed as a result of interaction of laser radiation with a target of this kind. Two types of problem are considered: a one-dimensional planar problem of the appearance of a quasistatic electric field because of the formation of a space charge near the target surface and a problem of the generation of a magnetic field by surface currents flowing because of the inhomogeneity of electron emission.
