Angular distribution of photoelectrons emitted at pulse laser irradiation

The analysis of electron-distribution formation in a metal irradiated with a laser pulse is given on the basis of the explicit solution of the quantum kinetic equation. The angular distributions of electrons emitted under laser irradiation of a metal surface are associated with the non-Fermi electron distribution generated by the laser action. The anisotropy of photon absorption in an electron–phonon collision causes a two-leafed distribution structure, which qualitatively distinguishes this mechanism of laser-stimulated electron emission.
