Stimulated Raman scattering coupled to decay instability in a plasma channel
- Department of Physics, Indian Institute of Technology Delhi, New Delhi 110016 (India)
A non local theory of Stimulated Raman scattering (SRS) coupled to decay instability in a plasma channel is developed. The primary Langmuir wave, produced in the Raman backscattering process, decays into a secondary Langmuir wave of longer wavelength and an ion acoustic wave. This diversion of energy, along with linear Landau damping of the primary Langmuir wave, slows down the Raman process. The nonlocal effects cause further reduction in the growth rate.
