Account is taken of results of computational simulation for a disruption of dense noble gas by electrons of a boundary layer at an irradiation of the metal larget by powerful picosecond laser pulses. It is shown that taking into consideration of an electric field of the boundary layer gives in essential magnification of concentration of inoculation electrons near a surface of the target. It ensures more quick weep of the ionization process. The dependences of a disruption time from an electric intensity of the incident wave, concentration of atoms of gas and high-frequency electrical pressure are obtained.
