Nonlinear excitation of photonikos and plasmons by high-power, short pulse lasers

摘要

Modulational excitation of longitudinal photons (photonikos) and electronLangmuir waves, as well as ion sound waves by an incoherent strong andsuperstrong radiation (high-power short pulse lasers, non-thermal equilibriumcosmic field radiation, etc.) in plasmas are investigated. A simultaneousgeneration of photonikos and plasmons are demonstrated. Furthermore, thekinetic instability is considered when a low frequency photonikos are generatedalone. Growth rates of these new modes are obtained.
