摘要：
The properties and excitation of solitary hump of electric potential of large amplitude, observed in experiment and propagating with thermal velocity of plasma electrons near foil at laser pulse interaction with it, have been described. This soliton has been observed at interaction of laser pulse of duration 1 nsec of power 10(14) W/cm(2) with foil of thickness 26 mu m. The excitation of soliton by nonstationary electrical field has been described for the first time. The properties of soliton has been described in strongly nonlinear case. The dependences of width and velocity of soliton on its amplitude at large values of amplitude have been derived. Both in experiments and numerical simulation it was shown that the width of soliton increases with amplitude growth at large values of amplitude.
