Strong Langmuir turbulence in a plasma which occurs in the field of an electromagnetic wave is studied by means of an electron probe beam. A modulation instability can be generated by exciting a nonlinear Langmuir standing wave in the plasma when the amplitude of the electric field of the pump wave is on the order of the threshold amplitude. An increase in the amplitude of the field of the pump wave generates a broad spectrum of plasma waves.
