The parametric instability of electrostatic waves in a homogeneous cold plasma, in which the electrons can acquire relativistic velocities in the field of the pump wave, is analyzed. An equation is derived which describes the parametric wave excitation without restriction on the amplitude of the external field. The condition for the applicability of the parametric equations neglecting relativistic effects is found. The growth rate of the waves excited as a result of the relativistic change in the electron mass is found as a function of the wave vector.
