Measurements of finite-bandwidth effects on a parametric instability

· Phys. Rev. Lett.; (United States)
The effects of broadband (stochastic) pump on the parametric decay instability is studied experimentally. The growth rate decreases with pumb bandwidth, ..delta omega.., as if only the fraction of the pump power within the resonance width is available to drive the stability, in agreement with theory. The saturated wave amplitude and suprathermal-electron production well above threshold are only slightly decreased (for bandwidths presently available, ..delta omega../..omega..9 or approx. = 3 x 10/sup -3/) in agreement with simulation calculations.
