CAVITON FORMATION AND SECOND HARMONIC EMISSION DURING THE INTERACTION OF MICROWAVE WITH INHOMOGENEOUS PLASMA
微波与非均匀等离子体相互作用过程中坑子的形成与谐波发射

The experimental simulations of laser-plasma interaction process by means of the microwave-plasma interaction have been performed in a steady state plasma device. The evolution of cavitom in the nonlinear interaction is experimentally investigated. The good agreement between experimental results and numerical calculation of Zakharov equation is obtained. The second harmonic emission spectrum is measured, and the mechanism of red-shift of second harmonic frequency is discussed.
