Experimental observations of nonlinear saturation of the two-plasmon decay instability
Journal Article
·
· Phys. Rev. Lett.; (United States)
Direct measurements by time-resolved Thomson scattering of the saturation of the two-plasmon decay instability driven by a CO/sub 2/ laser in an underdense plasma are presented. A time-correlated growth in ion fluctuations is also seen, enabling the saturation mechanism to be identified with the ion motions driven by the ponderomotive force associated with the large-amplitude electrostatic waves.
