Parametric excitation of charge density fluctuations in classical and quantum electronhole plasmas
Abstract
Parametric excitation by laser radiation fields is studied for both classical and quantum electronhole plasmas. Such plasmas may be characterized by several easily varied parameters, so that the behavior of the nonlinear excitation threshold may be investigated as a function of parameter ratios. The case in which the hole contribution is not negligible (when electron and hole masses are nearly equal) can then be studied. In addition, the case in which the particles are given a drift velocity by a constant external field receives attention. The Vlasov equation as treated by Sanmartin (1969) provides the basis for the classical electronhole plasma analysis, while an equation of motion approach in the second quantization representation of Tzoar (1969) is used for the quantum case.
