摘要：

It is found experimentally that the broadening of the pump-wave spectrum affects the parametric instability in an inhomogeneous plasma more weakly than is predicted by theory. The suppression of the absolute instability is only observed for a pump-wave spectrum width of 2 pi Delta f> 100 gamma, which is much greater than the instability growth rate gamma.
