Abstract

The optimum resonant angle for absorption and surface ripple at a critical density surface were observed by a measurement of the angular distribution of the reflected and scattered laser light from a plasma. The polarization dependence of the surface instability and the observed wave number are consistent with a theoretical analysis.
