Nonstationary parametric turbulence of a plasma

We have investigated the evolution of plasma turbulence initiated by parametric instability (by the decay of the pump wave into two plasmons) and saturated by induced scattering of the plasmons from the ions. We show that parametric turbulence develops in a dense plasma during a nanosecond pulse from a powerful neodymium laser, and is essentially nonstationary as a result of the oscillations of the noise about the turbulence level.
