Abstract
By considering a laser-induced dipole layer along the surface of a met al and its action on an electron of the metal, it is Shown that at mod erate laser field intensities of some 10(10) W cm(-2) energetic electr ons of a few 100 eV can be produced, which explains recent observation s of Farkas et al. [Phys. Rev. A 41, 4123 (1990); Opt. Eng. 32, 2476 ( 1993)] without necessarily resorting to the mechanism of Coulomb explo sion, taking place after the completion of the ionization process. [S1 050-2947(98)00601-5].
