Abstract
A new envelope-kinetic method for the simulation of Raman backscattering and laser amplification is presented. In the new scheme, the plasma wave envelope is obtained from the envelope-kinetic equation. For the self-consistent calculation of the kinetic term, a set of test particles is employed, and their motion is traced. The benchmark results of the new scheme against the averaged particle-in-cell (aPIC) show quite reasonable agreement while the computation speed increases by a factor of more than 10, depending on the parameters.
