Abstract

Photon kinetic theory provides a framework for the study of intense electromagnetic fields interacting with underdense plasmas. it is particularly useful when studying forward scattering four-wave modulational type instabilities. the most powerful features are its simplicity and its strong connection with particle beams, and the natural way in which broadband and angular spread effects can be included in the formalism. In this paper we derive the dispersion equations describing four-wave stimulated Raman and Brillouin scattering and Langmuir wave modulational instability for induced spatially incoherent pump waves.
