The classical kinetic equation for electrons in a dense strongly coupled plasma, interacting with laser radiation, is considered. The effect of strong ion-ion coupling on nonlinear bremsstrahlung and higher-order harmonics of the electric current is investigated. Particular consideration is devoted to a strongly degenerate plasma. Analytical formulas for nonlinear conductivities versus field intensity are derived for this case. These formulas are valid in the nonasymptotic region 0[lt][var epsilon][sub [ital E]][lt][var epsilon][sub [ital F]] ([var epsilon][sub [ital E]] is the electron quiver energy in a laser field, [var epsilon][sub [ital F]] is the electron Fermi energy in metals).
