Phys. Rev. Lett. 26, 688–691 (1971)Observation of Direct Nonlinear Coupling of Electromagnetic Waves and Electrostatic Waves in a PlasmaReceived 4 January 1971; published in the issue dated 22 March 1971 Experiments demonstrating resonant nonlinear electromagnetic wave excitation of electron-plasma and ion-acoustic waves in a plasma column are described. Direct verification of the wave-number selection rule and indirect measurements of the mode power levels are shown. © 1971 The American Physical Society URL:
